hi ive got a mk3 polo bread van and i tryed to put my sony headunit in there and it doesnt seem to have any power gettin to it i was wonderin if it was a common fault orr if anyone had any ideas ? cheers liam

Have you tested all the wires? Particularly the live and ground?

yeahhh tryed all the wires with no success as its a older car i thought the wires mite be arranged different to the newer headsets ?

you might have to swap red and yellow... or depending on wiring join red's (or yellow's) together and plug into car...
you wiring for the head unit will prob have bullit connectors on the red and or yellow power wire's so you can swap them and join them depending on what car you have...

get some wire and a bulb. put wire to an earth point (door hinge etc) and other end to wires in car with ignition off and with it on... the bulb should be in the middle of your wire so you can see if you have..
permenant live and ignition live... your intructions for your headunit will tell
you which way to put the red and yellow depending on what power you have...
