We had the factor RSE in our last 2019 Tahoe, but when we got our new 2023 Tahoe I knew I wanted to do a custom/portable iPad setup that allows full app access and portability between vehicles.
2 Apple iPad Airs 10.9 size
Lamicall Car Tablet from amazon
Two USB C black cables for charging ran through bottom of seat
Two Beats Wireless headphones with W1 chip
This setup can be run off the Vehicle Data package or using our iPhone hotspots
For front screen I used Carlinkit AI Android Box 8gb ram/128gb storage this allows plug in/play and downloading apps from Google Play Store for streaming entertainment. Front screen does use the built in vehicle speakers/data connection, and power source. (There is a slight audio/video lip sync from the Carlinkit AI Android box, but maybe future firmware update will resolve. Not a big concern as its usually used to watch sports on long weekend trips with kids travel teams)
This setup allows all three screens to be watching something totally different. Portability between two vehicles and all for less than $600-$1000, depending on iPad size/discount/sale you catch on amazon at the right time of year.
Overall family loves the setup.
GM really needs to open up the Google play store in the new Android/Tahoe stock headunit for the 000's of apps instead of using a Carlinkit AI Android Box as a work around. This Carlinkit AI Android box uses the wired Apple Car Play connection to run in three ways Apple Car play, Android Auto, or Android 12 tablet/phone mode for full customization.
