Hello This unit is exclusively for cars with a negative ground, 12V
Have you checked your car video player Rosen R5505 properly. If it doesn't power up, connections may have some trouble.
If your unit doesn't come up, check the 3AMP fuses connected in series with the main +ve power rail. There are three wires from the rear power socket, colured yello, red and black. Out of which Black wire is --Ve or ground.
Yello is meant for constant power +12VDC, and red is meant for +12v accessory supply.
Whe fitted in the car, the yellow wire is connected to the ON-OFF switch, to power the unit when needed and the red wire is connected before the ON-OFF switch, so that there will be power ot the control section of the unit to retain memory and all other previous setting levels. In otherwords, red wire must be connected ot the battery terminals, and yellow wire must be connected after the switch of the car. This is the wiring status when the unit is in the car. Black wire is meant for ground or cars chasis.
When the unit is powered ouside the car, the red and yello wires must be shorted and connect to the +ve and the black to --ve. Then obly the unit will live up. OK.
