I do not know any further info on this unit as my son has since passed on sept 21 so I dont know where connection manuals etc are. However all of the connections on the back are clearly labelled and All of the cables that were used are included. I know this workrd perfectly in his car (a C Class merc) and it will fit any car that has a dual radio slot. Is has bluetooth, plays MP3 via usb etc and reversing camera, plays dvds,and cds has a FM radio etc. HOWEVER I am unwilling to give any guarantee on this due to the fact if the purchaser connects it wrong they could cause faults. DUE TO THIS I am selling this as 'SPARES or REPAIR' as there are no returns for any reason. Please be aware of this BEFORE you purchase. I say again this item worked perfectly in all aspects before he sold his car on. Any further questions please ask
