Ok so Ive got the wincen unit in, and its a definite upgrade, but now i have the janus bezel and am going to build the system to replace the replacement system.
It will run android and backtrack, will be root, and will have the following features.
Dual core arm or atom cpu
Atheros wifi (madwifi ok)
Realtek hd audio out
Canbus reader/writer for wheel controls and other buttons
Hd radio in
More to come…
