A 3.5mm auxiliary input jack or plug will allow any device player to stream sound through your vehicle's stock sound system.
This video details the disassembly of the radio down to the motherboard. Extension wires are then soldered to the three possible inputs that can be tapped into - CD player, Cassette player and AM/FM radio tuner. All three of these inputs are clearly labeled on the bottom of the board as "L" "R" and "GND" for left, right and ground connections to the 3.5mm plug.
This hack will work on most stereos that use an analog audio input to the equalizer chip. In some cases, it is necessary to use a silent CD or cassette to trick the radio into reading sound from that respective input. For the best sound quality, a silent CD with the AUX connected to the analog CD lines is preferred, though modern radios use a digital CD signal which won't work.
The three methods are then tested in the vehicle after the radio is put back together and proved to work. The analog input of the phone/music player overrides the sound coming through the CD, radio or cassette. Some phones that feature headphone detection may not detect the cassette player due to the impedance.
This video was demonstrated on an Infiniti G35 with an OEM stock head unit with navigation.

This mod will only cost $1 for the cable, $80k for the electrical engineering degree and a toothbrush.
True...but here you got my video so no need for the degree 😉
A tiny correction, brother's toothbrush, so it should cost you nothing ! 😂
LOL
@@imsrini And wife's kitchen towel.
Maybe 80 hours on CZcams and some practice but once you get the basic electrical knowledge it’s a piece of cake
"Wanna fit an extra 12v plug?......first of all we remove this plastic trim.....then we drop the engine....."
Pretty much!
Today we're going to install an AUX jack into our stock radio, but first we'll need to remove the engine and transmission of the car.
That video is coming soon
These g35s are a nightmare for that

Haha
Towel was what was next to me otherwise I would have ran for the underwear 🤣
I love how detailed this video is but damn that's a lot of work.
Yeah because this car has the radio board really buried in there!
The hours of work distilled into 6.43 minutes. Amazing!
Yeah it was literally hours and hours
Right , this guy is a Champ n patient
Take a shot everytime he says „remove“👍🏼
Remove
Man, you're just a genius. All there is to it. Thanks for all these videos -- very entertaining and informative.
The problem with the phone volume all the way up is it will inject distortion from the output circuitry on the phone.
The best volume level on a phone is about 80% where it will be below clipping levels but still above levels where any loudness circuitry will be overridden.
Good tip, it depends how sensitive you are to distortion and what you listen to as well, most aux hacks I have done I usually feed the highest phone volume and then control the final output from the cars stereon
this seems like something that might be true on some phones, but not all
Thank you so much I had spliced into the amplifiers input, but keeping the stereo controls would be cool
This worked like a charm on my 2005 Pathfinder. I used the fm modulator inputs and it works great! I had purchased an after market iSimple bypass and it sounded terrible. Thank you so much!
Brilliant ! a fantastic guide thank you for making this excellent video and posting it for us. I knew there had to have been someone who had added an Aux input to an old cassette radio head unit . This is the perfect solution to enable classic car owners to retain their OEM head units and add music from a phone or tablet .
Yeah it sure works great and is cheap to do
you know i done even have a car but i still watched this for no reason
Thanks
Big thanks for the video! I have a 2006 G35 Coupe, so mine was a lil different. Plus IDK ANYTHING about electrical work, so small learning curve but ultimately I had to tap into the RCH-OUT and LCH-OUT then GROUND. Works great.
Glad it worked out
Thanks. After watching your videos I did this mod to my CRV and it works 👍🏾
Cool! What year crv?
@@speedkar99 2003 CRV. The only thing is that I have to turn off the radio before plugging in the aux into the phone, similar to what you did in this video. With the aux hooked into the Bluetooth adapter, the audio is very low and staticky so I don't use that adapter. Still cool mod and it's all thanks to your videos. Keep them up!!
You know what I learned from watching your video that you're pretty brilliant number one the number to it's too much trouble to go through.
This was my 1st and only mód to my old Mazda 6 which i bought 2 years Ago , after i burnt a bluetooth device with 16 pin conector to my radio homemade by some german guy selling IT on ebay by messing Up the wires (IT cost 30 Euros) i found a manual how to do this on old Mazda forum from 2004 , IT took 3 days, lots od cursing, 2 failed attempts, as i have never ever done anything with electric wiring or soldering, ale after i rebuilt the radio i was left with 10 screws , but it works after 2 years and i never gave Up, i Can finally say i have done something as good as speedkar99 did, car related :D (i didnt know anything about cars back then and now after All problems my old Mazda has encounterd through out that time i learned a lot, but your YT channel explains almost everything in the best and most simple ways car newbie like me could imagine)
Good to know you finally got it done and can enjoy your radio now
It would be good to route your internal CD input wires to a female 3.5mm jack, so you can use (and replace easily, if need be) a cheap and widely available 3.5 mm male-to-3.5 mm male patch cord. You can crib a jack from anything, and maybe secure it with epoxy or even silly-cone.
Yep good tip
Hey I know you get questions like this alot and I love the fact u engineered n test it out. But I'm just wondering if I could wire the aux in using a splice rather then taking the whole unite apart. Thanks for doing this btw I learned alot
Mad respect to anyone that gives this a shot and doesn't F up their entire system
Hey I did it....and it worked first try
I love that you never dropped the toothbrush
I bet you can AUX input hack your brother's toaster.
Haha maybe I have to try!
Make him have to press his brothers tooth brush to switch to the next song on his brother's toaster.
Wasn't that an aux in casette adapter you put in the tape deck? A hell of a lot easier and they work great.
But it's clearer without hissng
No one can ever call you lazy! Wish I could do stuff like that (instinctly)
True...I'm not lazy and like to get up and go! Sometimes too much haha
THANKS...
Worked for me, on my Bmw e46. I had spare time and nerves hahah
The BMWs radios aren't too difficult, I've done one and it was straightforward
@@speedkar99 what about rd4 radios? peugeot / citroen?
I wish the radios I am working with were so nicely laid out for the audio lines, all of the 80s Ford stereos I am working on are barely labeled at all, I was hoping for some test points at least!
I've tried soldering to 3 different pairs of Left and Right (plus ground) on the motherboard and nothing worked. In one instance the audio still came from my phone, in the other two times no audio played anywhere. This was with a 2002 civic's radio. Oh well. I had my hopes up for a cheap fix. Guess I'll have to buy a bright glowing head unit so I can use an aux cable. At least it was fun trying.
I have done this on my last few cars , I currently have it done on my Lexus sc 430 .
Yep, Lexus radios are easy to hack. Especially if you have the cassette deck
On second thought, think I’ll just spring for that new deck
@speedkar99 Love your videos! I've seen a few now and I can really appreciate your expertise and how clearly you explain how to DIY some rad stuff! These yahoos putting you down for how complicated this would be have no idea what they're talking about. They think they can just buy a can of Fix-Me spray and apply as directed and all there problems will go away. If they would just put in a few hours of learning how to solder and actually apply themselves almost anyone could do this. You've done all the hard, time consuming stuff for us so we can just follow your instruction. Once again, thank you for these videos!
Awesome video! If anyone wants to try this without ruining your cars radio or heater controls, usually the local scrapyard may have another radio that you can practice on!
Good advice. I do this sometimes. Practice on junkyard parts.
👍 Great ll book you in for install thanks 🙏
Why does the CD hookup have better sound quality than the radio hookup? I would prefer to use the radio hookup to avoid having to keep a CD on hand to activate that input if it could be made to sound as good.
You are AMAZING!!! Well done,but I personally would NOT try this at home ;) !
Awesome! Thanks very much
I remember that dirty toothbrush from the muffler video
-Pro tip: The G35 clock bezels pull straight out, rather than upward. It's pretty easy to break the tabs off removing them.-
Speedkar's way is perfect. Do just like him.
Unrelated: I sell those bezels on ebay to people who break a tab for around C$100, shipped anywhere in N. America. ;-)
Toothbrush makes a great panel popper
@@speedkar99 Yes, but it's best to pop from the top! If you look at the bezel, you'll find the tabs aligned longitudinally. Best way I've found is fingertips @ bottom of display and *_pull!_*
Nigga said I’m going to use my brothers tooth brush right here 😂😂
Yea I sure am!
The minute I saw the toothbrush I was hooked
Love your work... 😁😀
Thank you
Make a video connection of Bluetooth to 2007 Murano stereo please 🙏
GREAT JOB!!!
You should change your channel name to "The tooth brush Guy"
Thanks. Haha nah I like speedkar99
5:55 I'm curious why you inserted the RCA cassette to 3.5mm adapter for silence when testing the cassette leads, why not just use the 3.5mm off the cassette as your aux and save the laborious task of taking everything apart.
From my experiences with foreign cars that include combo cassette/CD players is that they are the most future proof but I haven't found a cassette to 3.5mm adapter worth bragging about. Can you recommend the blank CD aux input method as having better quality than any cassette adapter that can be purchased?
Cassette has Terrible quality compared to a CD input
TOO MUCH HASSLE I WOULD JUST TIE SPEEDKAR99 BROTHER ON THE PASSENGER SEAT AND POKE HIM WITH HIS TOOTHBRUSH WHEN I WANNA LISTEN TO SOME MUSIC
Hahahaha good one! Poor guy though
Subscribed. Interested in doing this, I’ve done it before by disconnecting the tape deck output and soldering a 3.5mm wire onto the input pins. I have a 2005 g35 with a different audio package, it has a cd changer but no tape deck so I will have to connect to changer or radio. Do you notice any interference from the input from the existing connections? How does it just override the CD/tape/radio? Also do you have to remove the gauge cluster to do this or did you that for another reason?
I didn't have any interference issues. Make sure you use a blank CD. The cluster was removed as part of a future video (maybe)
My 2005 G35 CD mechanism not functioning properly I can't use blank CD , so my only option is to use radio input?
Reminds me of Afrotek mods back in the day....and was that Misogi?
I'm.in but the pinout of the radio module isn't labeled lol. I'm nowhere near smart enough to trace connections so I suppose back together it goes
Google the datasheet of the chip
Can you use those Bluetooth adapters on a 2003 g35 sedan
I've a audi a4 b6 I have a connects 2 module. that allows a Sony cd changer to be connected and played through the rca leads. However I have a jack plug with rca connections on the end that I've connected these to the connects2 rca outputs and then plugged the jack into my phone. if I put a cd into the changer. I can listen to the music on my phone. However if a cd finishes my music goes of till another cd is playing which is shit... So do you know which wires it is that tell my hu a cd is playing. So I can hack these so the hu thinks a cd is playing when it's not and the multichanger does not require a cd .. If you have an email I can send you what I have.but I'm sure the wires are inside the don't bus lead and not the connects2 module. Or will it be easier to open the multichanger and hopefully it's just a case of glueing a microswitch connection together hoping that this will activate the signal so the hu when in aux mode thinks the cd is playing a disc.. Any help offered is appreciated. If you need any I more info itscraigsagar22@gmail.com
Yes
So followed the whole video, everything works(amazing video btw). When I put a cd in it plays my phones music. The problem is when I try a blank cd so there is no background noise, my radio says “Error” and ejects the cd. Does this mean I’m stuck with music cd’s or is there anyway to get the blank cd’s to work? Is it just the type of radio I have?
You need to burn a silent CD track
speedkar99 Ah I see. Thanks for the help!👍🏼
Yeah I’ll think about it.
Let me know
5:10
My phone doesn't have an audio jack.. 🙁 😓😖😖
iPhone?
Sorry iPhone people. You can get a Bluetooth adapter to work with this aux to work.
get a dungo
Life: 1
IPOF: 0
Hi ! Is it possible to do this to a Volvo V50 ? Thanks !
*MOST IMPORTANTLY! Get a cable with a SLIM connector. If your phone is in a case, a lot of these standard connectors won't fit with the case on!*
I would also recommend you get a cable that costs more than a dollar. A $5 cable from monoprice will have altogether better components, and it's worth it because this is not something you just want to redo when your cable shorts or gets crackly from age or weather.
Oml, I can desolder something broken and resolder on a replacement for something(have successfully done it with a broken internal gamecube battery) but whenever someone goes into the how the different circuts inside of a motherboard or whatever work I get lost and can't keep up.
Electronics is fun, the best thing are the datasheet for the chip that help you understand
2:10 Gotta get me one of them toothbrush pointing wands.
whats the difference between the radio and cd player? i prefer to connect it to radio, what would be the issues?
CD is clearer and less chance for radio interference
I'm sure it was fun but no way I'm doing all that. I had a company car many years ago that I could not mess with. I ended up buying a RF transmitter and a MP3 player. The RF transmitter needed batteries so I took a phone charger and did some dodgy connections to use that instead.
I will admit the quality was not the best but not a single screw or trim was harmed in the process.
Good non-contact solution
Good stuff
My motherboard doesn't have labels for left, right and ground. How can I idetify them?
Often you can find some schematics of your radio online. Between this video and googling the radio model I could find it in two out of three cars. I came back to this video to ask a question, unfortunately he doesn’t seem to be responding anymore.
I tried to do that, checked the motherboard but i found no labels indicating right, left or ground .
Any advise ?
Thanks
You'd have to start looking at the radio lines for inputs.
Or get the datasheet for the main chip
speedkar99 is hookup wire the same thing as electrical wire?
Why do this when you have an aux tape deck adapter?
Awesome video, almost wasted money buying a whole new car radio / cd player (and I would have lost my cassette player too!)
Where can I get your brother's toothbrush? Only thing missing
One dollar only goes to the part(s), plus the labor is probably 80Cdn per hour multiply by 8 IF everything goes right, final total comes to a hefty $641! 80 dollars per hour is what any auto mechanic would charge these days and probably even more.
For me, I have often fancied buying a home-use soundbar and a subwoofer with bluetooth connectivity and just let it sit at the rear shelf, plus an inverter to power it. Now that is bang for the buck!
Nevertheless, have always enjoyed your videos dear speedkar99, it is quite amazing considering that you don't need to refer to the factory schematics.
DIY doesn't include labour charges haha
A mechanic wouldn't touch this stuff, and frankly, most are unqualified. 120V home stereo stuff in the car seems like a good idea...until you get mad interference from your alternator through the inverter!
I checked to see if the upload date was April 1st for this little $1 hack……
Great job man but how did u identify the left and right wires pls
Thank you
If you Google 3.5mm jack pinout you can use the continuity tester on your multimeter to find out which wires belong to left, right and ground.
Didn't realize aux cables were usually aluminum, until I tried soldering them, guess I'm using alligator clips
Lol
another 'labelled' mboard! Mine has no markings, neither does the cd board. Any ideas?
Look up the datasheet
where can i get your brothers toothbrush. it seems very handy
Why to go through all this if I have a cassette player ??? I can get a cassette adapter for less than $10 including the cable. In addition, what's the make and model of the car?
Quality isn't as good and the cassette resets sometimes
Cassette quality is horrible compared to a hard connection
I feel like with all the work this takes an fm transmitter or better yet and FM modulator would pay for it self, be a safer option and not near as hard or complicated for the average person to install. Awesome fucking hack though bro!!
So I was hoping you could help me with something. I have an 06 Solara with an android head unit installed. I found a 4 wire aux port from an 07 solara at the junkyard and wanted to wire that into the aux input for the head unit. I bought an rca male to aux male adapter to connect to the red and white aux inputs on the head unit. I had used a continuity test on my multimeter to determine the ground left and right of my aux port. There are four wires, but the fourth one ended up not being connected to anything so I just left it disconnected. I soldered the three wires ground left and right to the aux side of the aux to rca adapter respectively. I plugged it in and opened the AVIN app on the head unit, but whenever I connect the aux to my phone, the phone acts like nothing is connected and the head unit plays a repeated thumping noise. No phone audio in the head unit. Any advice? I appreciate it.
Is that rca port meant for aux in or out?
Try a different phone without jack detection
@@speedkar99 Yes the ports are made specifically for that. The red and white are labeled aux in L and aux in R and the manufacturer eonon specifically mentions the use of the rca to aux converter I got will allow 3.5 aux capability. I dont believe I have a phone that doesnt have jack detection though. Any other common devices that dont have jack detection?
I figured out why it wasn't working. I ended up believing I wired it incorrectly or that the port wasn't compatible with my radio, so I bought a 3.5mm female to rca male adapter and plugged that in, and I got the same noise. I then tried it with a different phone and it played with no issue. I then plugged my phone into a Tundra with a stock aux port and it still made the same noise. Trying it with a different phone worked, so my phone is the issue. The previous owner totaled my phone and it was restored, so I guess my phone's aux port was one thing that was not repaired. Thanks for your help.
Fucking hell man this went deep
Bijeezuss you've done that before!
Yes
Finally; a useful thing that can actually be of use as battery powered wireless surround speakers or what not and solar charging could be an option also but it is cool for free amps that could serve as tri-amps also maybe. Or whatever; hey bud; maybe show how to use them as cassette head adapted for guitar input and so on. But you all know that what would really be cool; would be a junction that would be added to the fm antenna coax and ............... well that made as much sense as something that made no sense. LOL There are cassettes that have a head that sits upon the cassette deck head and the motor could be disconnected to get rid of the disturbance and that could work also.
For the cassette trick: You need to buy a cassete and remove the tape. Than just plug the phone in, put the cassette in the player and the music starts.
Cheap AND easy.
Exactly
bro nice😍👍
I wish to do that but I dont have much tools
It doesn't take much....screw driver socket set and soldering iron
Which car is this??? In my Nissan Versa, this is a 10 minute job.
Holy sh1t, $1, but 2 hours and a royal pain in the a$$
Do another Bluetooth module!
Good idea. It would be simple as adding the module to this aux input.
This will actually cost you one dollar and all your family relationships.
Ironic that the wire didn't work with the tape input, but would have if you had plugged the cassette adapter into your phone! LOL
True but the adapter won't have as good quality which is the point of this hack
@@speedkar99 Agreed, though it's interesting to contemplate a high quality 3.5-to-cassette adapter played through a fully cleaned and recalibrated deck. I mean, if you're feeding into analog anyway...
Wow just a dollar to completely fuck up your car. Such a deal!
wow, cassette player? Look how ancient this car is..
15 years old...
Some of us have jobs unlike grad students that have ample time to make CZcams videos lol
I did this after grad school lol
"too much work..."
How much time did you have invested in this project?
I'll bet it took less time than driving into/around town picking up a Bluetooth transmitter... Without the cost
Maybe some people prefer to be bombarded with _less_ microwave radiation. Also, Bluetooth is fallible in a dozen ways that a cable is impervious to.
Bluetooth fm transmitter will never give you the sound quality of a CD aux connection
@@speedkar99 agreed. For those who claim this is too much work, I would bet it took less time than going shopping, with better sound quality to boot!
They have cassette adapters you can use…
Those have worse quality than adirect connection
That's pretty awesome. That said, I'll just buy a head unit, less chance of fire and horrific disaster.
Good choice. This car requires an expensive dash kit for that.
@@speedkar99 It does, I had one years ago and I remember taking the dash apart like you did. Great videos, keep it up!
0:58
Looks heavy
Sounds heavy
Sounds heavy
& sounds heavy
This one has the GPS unit so it was quite heavy!
ghetto master
😃
Super lol at the AUX cassette lolol
The cassette doesn't give as good quality as a solid connection to the radio's sound input
@@speedkar99 I agree with you
oh. Well that was simple! lol.
That tooth brush ain't pulling its weight
Haha why do you say so? It looks worn...time to steal another
When I do max volume on my phone through the 3.5mm jack, it cuts it down to half after a while with some fucking warning about hearing loss.
Whaaaaaaat?
That's built into the ROM
@@speedkar99 Yep. And like most, my phone is bone stock and likely to stay that way. I actually had CM on my last (identical) phone, but it was buggy with no updates, and I'm not technologically advanced enough to roll my own, or inclined to learn...best to be good at a just few things!
Im going to report you to peta for the misuse of the toothbrush
Hehe
Why not just change the headunit instead?
The G35 requires a $200 dash kit to Integrate the HVAC controls, since it's all controlled by one board. So an aftermarket route gets expensive quick...
@@speedkar99 that's still cheap, compared where I'm at, priced at $479 = MYR1950 😣
It looks simple though
It sure is
Is this some kind of a prank? Who would go to this length to add an aux input?
Man 😂😂
U forget to pull the engine & transmission to take out your radio 🏃♂️😂
