Sirius XM Radio Antenna Mount

Your truck or company truck? Are you allowed to open it up at all?

 

Mounted mine in headliner above passengers side upper cabinet. Stick magnet to pickle jar lid and slide under headliner where it meets under cabinet. Run wire down to top of passengers door window across to and behind piece where Jesus handle is and then under glove box. Best reception I've had so far...

 

I've never installed a satellite radio in a large truck but when I installed one in my pickup truck I ran the wire behind some dash trim then up behind the rubber door gasket up to the roof. I had it like that for a couple years without issue. I got much better reception than my other truck with factory installed satellite radio.
