I recently bought a 05 Scion xA and replaced my head unit. It's a Kenwood DPX503BT. I moved it to the lower cubby on my dashboards console leaving the top empty. Now I'm wanting to install a Eincar Android 7" touch screen GPS/backup cam in the top cubby. I will not be using it for any audio whatsoever though. My question is, is it possible to run both units off the cars power/acc/ground harness? I want both units to work in tandem. One for music and phone calls, the other for navigation and backup cam. When I turn the car off I'd like them both to turn off also without the need for a switch.
If anyone can help here I'd appreciate it.
