Found this cable behind the glovebox and it goes under the door sills and to the back of the car it looks like but it wasnt connected to anything. Any of you wise briskodians know what it could be and weather or not I can remove it?

isn't RG58 an aerial coax?

I am going to go for either sav nav aerial, or a car phone aerial cable.

Car phone aerial.

Where is my car phone then!? Should it be there? Where does it go and can I remove it? :p

I don't have one of the sat nav aerials.

I've got that under my ash tray :( has a button at the end like a switch?

I had all the wiring left over from the previous owner. Pain in the arse that was! Was all wrapped around the back of the headunit.

Was quite funny...

I was driving along once and obviously the unit still worked and there was a chap in the car next to me, well his unit must of been on the same frequency because his conversation started playing through the car!
