I'm Pissed! 🤬 Beware of GM

Agree. This is an MVI problem.

When GM offered their own factory nav upgrade for 2019 and 2020 for IOS radio (which they then discontinued not even 2 months into 2020 MY), they gave you an SD card and an authorization code. GM would issue the reprogramming of the necessary modules to make it happen.

2021, the option never existed. The IOS radio also changes part #s for 2021 as well and 95% likely don't have the ability to upgrade from GM to factory navigation.

GM isn't in the wrong here. GM's systems issue programming updates and software #s based directly from the options your VIN presents with. Truck is a 2021 with IOS radio and w/o nav, that's the programming the radio receives.

I get that MVI uses OE radios for the swap, but GM has NO indication that your VIN was upgraded to have factory nav, so all the cal files issued are as the truck was built.

All I can say at this point? Pay the $75 and see if the dealer can call GM Techline and try to bring it back. Or, try to keep a cool head and see if the dealer is willing to split or eat the $75 to see if anything can be done. Or, move on and use Apple Carplay/Android auto and Google maps, Waze, etc. 10x better than factory nav.

GM didn't "steal" it from you, the dealer didn't "steal" it either. You went in with an issue, the truck was reprogrammed with the latest factory calibrations which means no nav.

Thank you for the info. To be clear, my truck is a 2020. So, the hardware is all there. Your explanation of the process prior to GM ceasing the program gives me a little hope. Everything about MY2021 is therefore moot as it relates to my situation.

As for MVI, they didn't swap anything. I sent them a module from my truck that is located on the passenger side, bottom of dash area, on the far right side behind the glove box. MVI then performed their magic to add factory nav, and sent it back. I then reinstalled that module into my truck, inserted the SD card, and voila. Nothing was swapped out. I chose to go this route to avoid fighting with XM if I'd swapped that module. It was the more expensive, and more time consuming, route to go.

You and I will have to agree to disagree on what constitutes theft. However, my point still stands that they can't claim to be a tech company when they don't behave like one. For example, how many times have you had a cell phone that's run an OS update and your 3rd party apps suddenly disappeared? I'm willing to wager that number is 0. Same here for me. GM should've known this could've been an issue of their going to be a tech company. Nonetheless, something was taken from me and I want it back. I shouldn't be compelled to pay. That is actually illegal. I did absolutely nothing wrong. I own my truck. It is not a lease.

Use WAZE, it has live traffic routing, has live updates from other users that show road hazards and where police are sitting.

That's a bit difficult when your phone is sitting in the wireless phone charger and my truck doesn't have wireless Android Auto or Apple CarPlay. I get the live traffic updates with the factory navigation, along with suggested reroutes. I don't really care about speed traps, etc. I go fast enough to not be a problem in traffic, and slow enough to not get ticketed. That's +4 in surface roads, and +8 on the freeway.

The path for resolution for this goes thru MVI. I understand you're pissed at GM, but, how are they to know what aftermarket vendors are doing to their firmware to make the aftermarket devices work? Now, as far as MVI is concerned, it might be helpful to assume positive intent - it may very well be that the GM update that broke the system was not anticipated by MVI - and MVI needs to figure this out, not just for you, but for anyone considering buying their hardware. There's also no guarantee if GM winds back the firmware update, that the MVI system would then work.

Its also a new update from GM, and I doubt that GM gave MVI any heads up the changes were coming. Give MVI a little tine to fix this, or at least to communicate to their customers what the modification path looks like. MVI has to consider that this might be an ongoing process, where GM updates , the MVI mods break, MVI sends an update, and on and on. MVI has a problem. Unfortunately its your's too.

I'm not a tech guy, so thanks for your input. To answer your question, a possible resolution would be to treat the OS in a similar manner cell phones are treated. How many OS updates have you been through where 3rd party apps are not affected? I don't know the exact number for myself as I've been dealing with that for over a decade, but I can't recall ever losing an app unless I deliberately deleted it.

GN2018 · February 4, 2022

You may not have lost an app, but it’s not uncommon at all to have the app error out with a new OS update. And as for being a tech company, how often have you ever seen Apple (a tech company for sure) allow a module to be removed from its phone and allowed a third party to perform “their magic” on it and still support the product? In fact, their products are highly locked down.

I think your resolution will end up being with MVI. They need to support their process which is apparently not supported or coordinated with the manufacturer.

I can't speak about Apple since I have never used one of their products. It is my understanding the Android OS does allow developers to do things, though.

There are also 3rd party companies where you can take your device for repairs or modifications and the manufacturer still backs the phone. Those company's employees do receive training from the manufacturer, just like a dealership's technicians do. Iirc, one such company is called UbreakIfix.

Hopefully mvi will give you a discount on reprogramming the module again. Got a question: did reflashing the module actually fix your camera problem?

So you'd rather spend several hundred dollars for a junk Nav program that'll get overwritten instead of a $10 USB cord? Ok. Gotcha. By the way, wireless AA or AC is junk, too. Drains the battery quickly so you need a cord anyhow.

GM, like Apple, has their software as a closed system, meaning that it can't/shouldn't be altered by unauthorized parties. Apple iOS used to be hacked, called "jail breaking", by hackers to turn on functionality that was in the operating system but not turned on by Apple. When Apple sends out a new update for iOS, it wipes out the jail break. In a similar sense, GM does not know that additional functionality has been added to your truck. They only know what they know by what is assigned to your VIN. So when they reflashed your module, it was what they have marked down to your VIN. When someone gets official GM accessories added by the dealer, and it involves flashing some software, I think it gets added to your VIN so that in the future, any reflashes should have that change included.

IMO - when MVI updates the module for NAV, they should either "lock" the change, or let GM know that the change occurred so that it can be added to your VIN. This would avoid future issues with software updates or reflashes.

None of this is GM's fault. YOU had an aftermarket sourced program installed into your radio. GM can't do anything to restore an AFTERMARKET program, even if its "GM" software.

You took it in for an issue. They reprogrammed the modules to the latest FACTORY calibration. The truck was built WITHOUT NAV, so that is what goes back in.

Sucks to be you.

I’m curious my newest vehicle is an 15 CRV. When I unplug from the USB my phone switches to Bluetooth within a couple of seconds while I’m plugging in my earphones for my walk. When I get back from my walk it switches back to the vehicle. Is that just an iPhone thing or do other phones work that way? Iv only used iPhones. Question 2. I thought CarPlay used your phones navigation through the dash display. As I stated earlier I use my phone for everything, don’t have any problem with the small screen. My phone navigation has saved my from more than a few traffic jams. Especially going through Houston or Atlanta.

Switching to bluetooth after unplugging may be a function of either your phone or your CRV, I'm not sure there. And it may depend on the settings of either one, too.

Regarding CarPlay (and Android Auto), it does use your phones navigation on the infotainment screen, along with other Apps as well. CarPlay and AA basically mirror your phone's screen on the radio screen. Some apps that work with this are Maps, Waze, Spotify, Apple Music and others. Instead of fumbling around on your phone's screen, you can now view your Maps, or select songs/playlists on the larger radio screen instead of fumbling around on your phone. It also means you don't have to have your phone mounted on your dash to see it. Everything is on your radio screen now.

Good points here and clarity. My phone has had many updates and retains all downloads though updates. Not all from the apple store that I can recall. Car companies have let it know for a long time they want all services and repairs done at the dealer. There’s bill in congress now to change that.

I've had apps that have quit working or required an update in the when my phone's OS was updated. It is usually up to the creators of the Apps to update their product to be compatible with the current OS. Similarly, it should be up to MVI to create a product or product support that will keep working when a vehicles software is updated. I still don't see this as GM's issue, but MVI's.

The 3rd party apps might not disappear but, I've had some that do not work right when the new update was down loaded. That is not OS companies fault because the app quit working that is the company that made the apps fault. So do you go complaining to OS company or the app company for it not working?

My understanding is that all new GM trucks starting with the 2019 models. If you don't order the option (NAV, Trailer Brakes, and others) from the time the truck is built. GM has basically made it so you can't go back and install them. I know you paid for NAV to work in your truck but when you asked them to fix the camera and they needed to update the software. GM will only let the dealer upload the software version that is assigned to your trucks VIN. Even paying the $75 to get an answer from GM at this point is probably a waste of money because I serious doubt they will change anything from the factory settings. I know that's not the answer you want to hear.
