CarPlay and Android Auto run on the phones, the head unit in the car works like an X server, i.e. all it does is display what y9our phone projects. The firmware in the head unit can only be updated by the dealer, GM doesn't have over the air updates like Tesla does. Are you having a problem with CarPlay or are you just curious?Can someone tell me how I check the version of Apple CarPlay installed in my 2019 Volt? Also, how do I upgrade my version of Apple CarPlay?
Yep I’m having exactly the same issue and is only in waze when is connected by carplayOn our 2017 Volt Waze on Apple Carplay is showing our speed at approximately half of the actual/real speed. Just started happening a few weeks ago, not sure what the cause could be or what changed. I have googled this and see others have experienced this same issue, can't locate a fix. Not a major issue, wondering if anyone else out here has experienced this.
