hi guys, im driving a 1996 e38 long wheel base versionit came with an old 4:3 ratio tv, i have been looking around in the boot for the amplifier unitbut all i see is the tv control unit and cd changer. do u guys know if they came without amplifiers? or is it located at another place in the car. i am asking this because i am inteding to buy an aftermarket unit. but am unable to locate the cable pin type. thanks guys
