Re: Sirius Radio Antenna Wiring
I have XM, installed after purchase without the NAV display.
I had a proffesional install done, but they walked me through after where the wires went. They said it was impossible to use the existing antenna so they put the kit's unit in front above the windshield.
The wires from antenna run inside the space between windshield and car frame and enter the car where the glass meets the hood. Wires hide under dash and center cupholders, only coming out where they wire into the XM reciever and outlet. The Reciver is mounted right in front of the shift lever, does not interfere at all, and is powered thru the Power Outlet.
This was basic installation costing 34 and some change. The system has survived 3 months and plenty of outdoor weather.
I'd say forget the rear mount, to much wire to hide. The front mount doesn't seem to interfere with the radio antenna or a Garmin GPS unit at all. I use an 2 way adapter for the power outlet to use both GPS and XM at once. Probably completly illegal and potentially unsafe but the only time I use GPS is longer drives where XM is a must!
