GMC 2020 Sierra 3500HD
—
I received the device today, got it connected and...it kinda worked. It told me to connect it up via wire but it still connected wirelessly and started playing music from my iPhone. I could not access the CarPlay interface but again the music was playing.
I updated the firmware and no change. Now, with about 10 attempts to re-add my iPhone to the device via bluetooth, I got the CarPlay screen to show up, once. After that it went back to the old behavior of playing music but no CarPlay interface to use.
I don’t have steering wheel Siri control while using this device like when it’s connected via lighting cable.
I will reach out to the support folks in hopes of getting some assistance but based on this thread my expectations are low.
