Twice now on my 2017 Volt the infotainment system has locked itself up. No sound, can't change the radio station, won't recognize the attached iPhone, seems to think it has a bluetooth connection even when the phone is off.
I searched the forums and there was some discussion of TSB #17-NA-025, but if you read to the end of the thread this turned out to be a dead end for Volt owners. Plus the discussion seemed to center around USB sticks.
Simply stopping and restarting the car a moment later won't fix the issue, but it's OK by the next morning.
Has anybody else encountered this?
Yes. I have posted about it before a few times and have reported it to my dealership and directly to GM. In all instances they either cant find a fault or blame Carplay/Apple for the glitch. Its annoying because you really cant change anything, channels, radio/media and the OnStar button has no audio either which has the potential to be a safety issue. I suggested to them that we needed a "reboot" option for the infotainment system but I wont hold my breath on that one ....
I have been able to reproduce this error a few times, typically by plugging in the iPhone to a USB port before switching on the car. If the Carplay splash screen is displayed on your phone before the mylink home-screen comes up on the dash then you maybe have a 50-50 chance of this happening to you. sometimes you can seem to clear the issue by playing around with the home button and rotating the volume button or holding down the button as soon as your mylink audio comes on but its not a consistent fix and doesn't always work, or perhaps its even a coincidence.no way to tell ... just happy the system works at that point.
I now try to make sure I enter the car and only connect the USB cable after the car has booted up the infotainment screen and the problem does not seem to occur as often ... although it does happen occasionally. Its definitely a glitch somewhere between Carplay/MyLink systems but apparently its impossible for anyone to nail it down.
I have also recently started using an Android phone (tethered to my iPhone dataplan) so I can get Waze on my screen. This same problem has not occurred while using Android Auto so far. not sure if this means its a Carplay only issue or if I have just been lucky so far !
