Hi, just purchased XM Radio and I am looking for any tips or suggestions for installing an external antenna. I noticed a plug on the rear portion of the exterior roof that looks like it could be used for mounting the antenna or fishing the line down into the rear headliner. Have you used this for installing the antenna or do you have any other suggestions for an exterior install that will give a clean appearance with no wires visible?

 

On the Range Rover I mounted it just inside of the roof channel so its pretty inconspicous up top, then ran the wire down the weather stripping around the rear gate. At the bottom of the gate, ran it forwards underneath the side trim. Followed that allll the way up (door sills were the toughest part), up to the dash, and the excess wire is hidden behind the dash.

No visible wire. Granted its a Range Rover, so I don't know if you have seaming along the side interior trim, but I would imagine you do
