What place you guys think is best to put this on the vehicle. I want it to look the cleanest and not obvious. I was thinking leaving it inside where the front dome lights are because their is a lot of room up there but figure the roof will interfere with the signal. I don't have a sunroof So I can get it out through that.

 

When I had my XM unit I mounted the antenna inside the car, on the front center portion of the dash. I never had any issues with getting reception and you could hardly tell it was there.

 

Hmm maybe I will do it on the left top portion of my windshield. I have my Viper antenna on the right and it will add some symmetry.

 

I mounted my sirius antenna on the left side of the roof, and ran the wire down the weather stripping of the windshield, down to the cowl, and back towards the mirror. I ran the wire inside the weather stripping of the door until I got the wire inside. You can't see any of my wire.
