OK - first I couldn't decide - General, How-to, or Audio - but, I'll just start here...

Anyone that has added an XM system, which is easier to route the antenna wire to the rear roof area - drop the headliner or pop the door sill covers??? I'd appreciate any tips or how-to's on either option...

I only want to do this once - geo

 

I put a XM and CB antenna on mine and dropping the headliner down isn't hard. You don't have to drop it all the way, just on one side so you can get your hands in there.
