Hi, yes you can wire in a camera for reverse parking. It has a mic built into the facia for BT and when tested works well, seperate mic on A-Pillar would be better though. You have to shout abit when driving but the other end seems to hear me fine and they come through very clear to me. It's 45wx4, 3.5" touch screen and got a DVD player, SD Card reader, USB, built in TV tuner, BT, radio. comes with remote and a 12 month warranty. Iam very impressed with it so far cause i wasnt expecting that much from it tbh. Got my iphone setup via the AUX RCA to 3.5mm audio jack, so i can stream any sound from my iphone through the stereo, also can attach anyones phone, mp3 player or PSP or any device with a 3.5mm audio when they get in the car and stream music off there device. Only got Philips rear 6x9's and 13cm Pioneer front speakers and the sound quailty is pretty good. Just need to get my amp and sub now.

Heres my little media centre
