- I go through the steps of replacing the CMU with an ebay bought unit from a wrecked 2018 Mazda 3. Those who "enjoyed" my HOTAS repair video should find this in the same vein.... with a higher budget.
This is the best repair video I've ever seen man!
Most brutally honest repair video. I love it.
Best repair video ever!!!
Thanks for this; it was very helpful. But just as a head-up, for anyone else trying this... there's really no need to go through all the business with the glove box, taking it apart, and going at the trim from underneath it. Just use the cheap trim-removal tool from Amazon to pry out the trim. It comes out fairly easy without all that. Start prying from the end over top the glovebox, and work your way up to the air conditioner vent area. It's really not too bad! The rest of the video was very helpful!
I'm about to do this and thank you for your comment! So, I don't need to fully open the glove box and just start taking the trim would be good enough?
@@asukas6184 Yup, exactly! I did it earlier today, just before I made my other comment. You definitely need some sort of trim-prying tool, but with that, no need to drop the glove box down. Just start prying above the glove box and work your way up. I was surprised at how easy the whole process was!
@@davidschneider129 thank you! I don't have prying tool and couldn't push the trim from behind... so I ordered some from Amazon! If MAZDA is responding well enough for CMU issues, I don't have to go through this by myself though. 😡
@@asukas6184 For sure! To be fair, I’ve been happy with the car otherwise, but yeah, the infotainment system had been trouble practically since I’ve owned the car.
@@davidschneider129 Exactly the same here. I loved my car until this infotaiment system failed. After that all responses from MAZDA, corporate office and dealership are really sh*tty. Just like this video!
Love the video as that is how my car repair often go!!
2016 Mazda 6, constant reboot with or with out Nav card. Assuming Nav card is causing the issue like you mention in a reply but have a updated used CMU from ebay (sw 74.00 xxx) Do I need to have the Nav card just to boot up and run all the functions other then Nav? Will the updated CMU work with my car as some say the CMU is mated to the car. If I try to use my old NAV card will it screw up my CMU?
Thanks and still laugh when watching your vid.
Lol best language video
Brilliant
This is the greatest how to video ever 🤣
Dude I’m laughing so hard
Glovebox confessions…..🤣🤣
Hey man, thanks for the video. Do you know if I were to order in Australian CMU? Would it work with my North America unit?
Car not unit
@@Resolve_DigitalMedia i ordered an American unit and it worked in Canada so I don't see why not. You'll need to go into the settings and change u of m from km to Miles, and liters to gallons etc though.
hey, where'd you order from? i'm from ontario as well and having the same issue
Ebay for the CMU. Turned out NOT to be the CMU, but 2 different issues. Issue 1 was the camera itself. Technical Service Bulletin# 09-031/20 . they recommended replacing the camera but it didnt need to be replaced, i simply relocated the wire as per the bulletin. All you need is some contact cleaner and simple plastic removal tools for the trim. This is for when the camera is distorted and malfunctioning while shifting to reverse. The second issue was the system rebooting itself constantly. Turned out to be the NAV card of all things. I downloaded the mazda toolbox software and purchased the new map packs, installed them on to the NAV card and haven't had an issue with anything since. if by chance you DID need a CMU i do have the one i removed still.
Also for the camera fix -go to the dealership and purchase the materials for the TSB. It'll be some rubberized foam. Buy the high quality contact cleaner, not the shit from canadian tire. Recommend the wd40 contact cleaner , i think it's around $20 a can. Also while at dealership buy some spare door trim buttons because you may break one or two while removing trim.
@@jonnocrap hey! was curious if you still had that CMU you removed
@Cynersi yep, turned out to be cable interference mucking with the camera and navigation card mucking with the rebooting issue. Cmu is fine.
@@jonnocrap would you wanna sell it? mine just pooped out on an update loop for no reason
Did you need to sync anything after or did it automatically work?
Im in Canada and bought the CMU from the US, so i had to change the unit of measurement etc but otherwise it all worked perfectly - plug and play.
@@jonnocrap hey! So I know this is couple months old but do you know by any chance is that CMU reverted your "updates" if your dealer did any to your system? Basically did you notice if you were on the same version? I would assume so since .. well its the CMU but who knows with the fuckeryand if the updates install somewhere else ( like in that grey little fucking thing you have behind your glovebox *which is linked to the radio in some sort*
@@coaxkeqc the cmu I installed had a newer version of the software on it than I had on mine lol . I forget what version it is, I'd have to look. I avoid the stealership as much as humanly possible so I've not had the software changed or buggered with. I did flash the nav card and reinstalled the map packs as it gave me some issue but that solved the problem
