Has anyone done any aftermarket stereo and/or speaker/woofer upgrades in their ZR2?

My system prompted me to re-login to my Google account, which took a couple tries to connect. Not sure if that was because I had did a soft reboot a few days before.
 
are you on Android 10 or Android 12?
12, mine updated last fall when they pushed it out. But my wife's Tahoe never updated and still shows 10 and says its current.

Try a soft reboot holding down the end call button on steering wheel for 10 seconds and see if it refreshes the system to allow downloads. It won't update to 12 using this method.
