You have the factory fit Highline audio system, the two boxes in the spare wheel well are the video module on the left as you look down on it and the radio tuner on the right.
You say you still have the Navigation computer CD drive in the car, that means all you need to reinstate the original system is the dash mounted Alpine 'Bordmonitor' which comprises the 4:3 TV screen and radio controls. It is a dumb display device really as the radio tuner that receives the stations and tunes to them is in the spare wheel well.
It all depends on how the Android system was plumbed in, it should just be a case of removing the old unit from the dash and reconnecting the bordmonitor with any luck. There are usually plenty available on ebay.
thread moved to the I.C.E section BTW
