Forgot to mention the round end connection has 2 release clips either side and has a pin in the middle. Looks sort of similar to a radio ariel connection, but i've checked both the CD and built in sat nav unit and all cables are connected.
Not sure where else this cable can reach to. Any ideas anyone? Thanks
You sure its not for a cable operated speedo ??
I had a 406coupe and it had 2 aerial cables and they both worked ....
