ihave a sony head unit but it wont keep the station i tune in theyve all gone next time i get in the car any one help it would be much apprechated :?

have u got a perminant live at it

have you used the standard wires in your car or run new ones? did u connect them straight to ur head units loom or buy a converter? it may be that you have both the 12v the wrong way round.

pull the head unit out, swap the red and yellow wires over so youve got a red/yellow and a yellow/red one
