Infotainment bugs?

UncleDave · October 13, 2019

Really just a rant, as I figure there's no fix for this...

I have experience with the buggy center stack/infotainment system in my 2014 Volt. Today I experienced my first bug with my 2019 Silverado Custom with the base IOR system. I had the iPhone plugged in, using nav via Car Play. Suddenly the system decided to drop both the Car Play and the Bluetooth connections, Car Play closes and the icon turns grey, and I couldn't reconnect the phone to the system at all. Neither USB nor Bluetooth worked.

Whenever the system would crash on the Volt, if it didn't reboot itself (which it would sometimes do while driving), I would have to "reboot the car" by parking, shutting the car off, getting out, locking the doors, unlocking the doors, getting back in and starting it back up, after which everything would work again. Lo and behold, I did this with the truck, and everything started working again.

Nice to know the same old GM software bugs are alive and well in 2019... Is there a way to do the truck version of Ctrl-Alt-Del without having to perform the Chinese fire drill?

I have a 19 Trailboss and a 2014 Volt too! I've had to pull fuses on the Trailboss when the 'reboot' procedure you described doesn't work. I don't remember the number, but the fuse for infotainment is on the passenger side fuse panel. The fuse puller and spare fuses are on driver's side fuse panel.

I've also disconnected the negative battery terminal to reset the whole thing. I prefer the fuse method, since disconnecting the battery jacks with my mileage reporting.

Well, today I lost all phone connectivity again, but this time the screen went blank. The volume control still works but I cannot use any other functions. The backup camera displays when I put it in reverse, but nothing else does. If I shut the truck off and open the door, the display will appear for a split second then fade out. The "reboot" procedure doesn't restore it to normal, so I'm going to try the fuse pull method.

You would think after all these years they could fix their stupid bugs, but apparently it's not a big enough problem for them to put much effort into it.

Well, the Infotainment 1 fuse pull procedure works like a charm. I just hope it doesn't happen very often as I don't want to wear out or break the trim piece or plastic clips by removing/replacing the fuse panel cover multiple times. Really wish GM's programmers would get their act together and fix old bugs before introducing new ones.

I've left the trim panel off for now. I will replace it if/when a permanent fix is discovered. Fuse #F-58 is the correct one to yank out for me. F-41 is also listed as an infotainment fuse. Make sure the truck and infotainment is fully off, which may require opening and shutting the driver's door after the ignition is off if you're reaching in and turning off the key from the passenger side.
