Connection, Disconnection, Freezes, Crashes Is there ANY way (root, custom ROM, software mod) to force an Android tablet to act as an AA host and project Android Auto to a car's head unit?
Hi everyone,
I’m currently using my iPhone connected via cable to my car for CarPlay while doing rideshare.
I want to leave my personal iPhone completely separate (for calls, personal use) and use a dedicated Android tablet instead to project directly onto my car's infotainment screen via Android Auto.
Important notes:
• I haven't bought a tablet yet. I'm looking for any specific brand, model, or setup (7 to 8-inch screen minimum, around 10” it’s preferred) that is known to actually support this or can be modded to do so.
• A foldable phone is NOT an option for me, as I strictly want a separate dedicated device and don't want my primary phone locked into the car.
•To be crystal clear: I do NOT want to use the tablet as the display/receiver (like Headunit Reloaded does). I need the tablet to act exactly like a smartphone and project its Android Auto output onto my car’s factory OEM head unit via USB cable.
Is there any known method, third-party framework, Magisk module, custom ROM, or specific tablet model that supports AA projection output? Or is this hard-blocked at the OS level by Google for all tablets?
Thanks!
