I have a new car head display unit 7" for a car it was from overseas and has no brand name, on the back it has a blue wire which says back on it. Where do i connect it to ?
Its just for the amp remote it goes no where unless you have an amp

what you have there is a good panasonic head unit. the solid blue wire is going to be used for an automatic antenna.
Yellow- Constant Power (keeps memory for your clock and presets)
Red-Switched Power (turns your radio on when you turn the key)
Black-Ground
White- Left Front speaker (+)
White w/ black stripe - Left front speaker (-)
Gray - right front speaker (+)
Gray w/ black stripe - Right front speaker (-)
Green- Left Rear Speaker (+)
Green w/ Black stripe Left Rear speaker (-)
Purple - right rear speaker (+)
Purple w/ black stripe - right rear speaker (-)
Blue with white stripe - power out, (commonly used for the amplifier turn on wire, or antenna wire.
you may have orange wires in your harness,
or brown ones. these you dont really need
the orange wires are for your dash board dimming lights
and the brown one is for Tele, Muting.
what kind of car do you have, i can give you the wire harness colors

i think that the red wire is the acc wire but im not 100% on that because you havenot witten what model the radio is
anyways if it is the acc wire then connect that to a 12volt supply and see if it turns on all other wires must be connected though ecept for the blue wire which i think is the remote wire for a amplifier

You will need to hool up the blue and white wire will need to be connected to the amp turn on in the vehicle. Hopefully you are using an installation harness to make your job easier. The vehicle has a small amplifier in it. it does need to be turned on when you turn on the stereo.

The antenna generally will not retract until the power is turned off at the deck or if you turn the key off (which turns the deck off).Your deck may have a selectable dimmer function in the settings menu you should be able to set it to automatic and it will handle the dimming on its own then.
