Mine was already in the ISO connector at the back of the radio, works fine with a Blaupunkt Travel Pilot.

do you know what colour the wire was. ive a green/purple one on the iso plug which doesnt seem to be used at mo.

no joy with the spare wire at iso connector.any other suggestions. this is really frustrating as its the last connection i need to make.
