I am thinking of adding Sirius radio to my 03 expedition, has anyone done this? Any advice on mounting the antenna and routing the wires would be greatly appreciated. Thanks

 

I have a Sirius unit in my 03. I run the antenna on the inside of the truck in the center of the dash, as close to the window as I can. I have had ZERO problems with reception. As far as running the wires, just pull them along the window line, tuck them under the dash, and then to where ever your unit is.

 

So you didnt mount the antenna on the outside like they recommend?

 

I have a Sirius unit mounted in my F150 and my Explorer. I ran the antenna under the dash, up the a-pillar, and the wire exits where the a-pillar meets the roof and the antenna is a magnetic mount. I did mine on the passenger side. In hind-sight, I wish I would have routed the wire on the driver side. There are some roads with over-haning branches for long distances and the reception is not that great, however if I drive more towards the center of the road, so that the antenna has better sky coverage, the reception is a lot better.

 

Nope. It is in the inside.
