XM/GPS + Shark Fin
Alright here is my plan.
I currently have a Pioneer Avic-D3 with XM radio & GPS - but I currently have the two satellite antennae on the roof near my hatch. I just ordered a shark fin antenna with the hopes of running BOTH satellite receivers under the fin (I measures, it will fit). But, I want to run the wires through the OEM antenna base. Question: Has anyone removed the antenna base? If so, do you have to remove the roof trim inside to route the wires? I've looked at the factory repair manual but it's a bit confusing. Any help would be appreciated! |

I have XM in one car, and Sirius in the other two. In all cases, the satellite antennae is either on or under the dash. Have never had any problem with reception. My point is that they don't have to go on the roof or even outside the car.

I'm kind of torn as to what to do. The only reason I am doing this is because both satellite receivers are on the roof and have scratched the paint. |

Another option is to put it in the driver's glove box. I just installed an Eclipse AVN2210p and I decided to put the GPS antenna in the drivers glove box. I popped the trim to the right of the ignition switch and cut a notch in the lip that's under there. The GPS antenna cable and ipod cable are completely invisible when the glove box is closed and I like the idea of keeping the GPS antenna out of view. The third picture below shows the GPS signal strength with the antenna in there and the car in my garage with the steel garage doors closed. Cable routing: Trim back on: GPS signal strength: |

Thanks for the pics CTScott. I wonder if XM would get a good signal under there? May as well find out! lol

I also have both my GPS and XM module antennas under the dash - mine are to the right of the gauge cluster tucked between the dash and the air duct (without restricting anything) secured with a little silicon caulk, and they work beautifully and are fully hidden

Sounds good, I will try and find a spot under the dash for them. Do you think 3M adhesive would be fine to secure them and not fall off? Or maybe some velcro?

I dropped my headliner to remove the antenna completely. In short, there isn't any room to route wires through the hole. It is a square hole that fits the square antenna mount/bolt, with no room to spare.
Do the under the dash thing.

I put my GPS under the dash - works great. Put XM under there - it cuts out way more than it used to. Any suggestions? Both receivers have the same line of sight so I'm not sure what the issue is.
EDIT: Would putting a metal sticker under the XM antenna help? Mine came with a small sticky pad that is metal, but I haven't tried it. |

Putting the metal sticker, or better yet a flat piece of metal larger than the antenna might help, as it will give the antenna a ground plane. |

Just as an update even though the thread is oldish now - I had to remove the XM antenna from the dash. It was cutting out way too much. Seems the GPS 'locks' onto satellites whereas the xm needs a constant line of sight or else it goes wonky.
I tried an experiment and it was cutting out moreso when I was travelling in a Southern direction. If I was going North, it would be fine. So it leads me to believe the satellites are broadcasting from the north and the top portion of the car is cutting of some of the line of sight. Anyhow ... I moved it back to ontop of my hatch and everything works fine again. I'm still thinking of getting the sharkfin to hide the antenna, however. |
