Here's one of the Starmate installed in my coupe. Removed the ashtray, dremeled out a couple of areas so the radio sets deep enough into the cavity for the door to completely close.
Antenna, sorry for the poor pic quality. The car is covered in the garage. Just used a piece of metal banding material, bent at 90 degree at the top. Mounts to the two bolts that are already on the rear tub wall. The mount takes the antenna just below the top of the rear facia, above the inboard taillamp. The mag mount antenna stays on the metal band, I wound a couple of pieces of electrical tape around it to make sure it stayed on. Passed the anntenna wire through a small hole drilled in the tub into the rear compartment, its behind the carpet material. Then sealed it with silicone. I'm going to make another mount soon, that has a piece of metal on the top about 3 in. square to rest the antenna on. Clean it up a bit. Not that anyone will ever see it.

C4Cruiser,
What I believe you are talking about is not quite correct.
The Unit broadcasts a signal and your car radio recieves that signal when tuned to the right freq.
The adapter you mention makes a direct connection between the unit and the radio antenna (with adapters) so there is no interferance with outside radio transmissions.
It does not turn your car antenna into a satellite antenna or replace the satellite antenna.
However, I could misunderstand what you are talking about.
PS, my Sirius works great with the antenna behind the taillight as mentioned above...

According to the adapter instructions, it does away with finding an unused FM frequency on the car radio side; you simply set up matching freqs on each radio. It does do away with the basic magnetic antenna you get with the Sirius car kit. The car radio antenna acts as the Sirius antenna, the signal goes thru the adapter to the Sirius radio and back to the car radio.
What it's supposed to do is do away with the typical hiss you get at higher radio volumes along with interference.
Unfortunately, you need adapter cables for the car antenna lead and from the car radio to the Sirius adapter. The Sirius adapter uses the old RCA type antenna connections and the GM antenna and head units use a new style of connector.

The Sirius "FM Direct Adapter" (part number FMDA25) goes inline with the car antenna and acts as a cable splitter between the Sirius radio unit and the car radio. The adapter has a cable that plugs into the Sirius radio and the car antenna lead plugs into the adapter at one end and another lead goes from the car radio to the adapter.

This is incorrect, it does not replace the Sirius magnetic antenna. It simply transmits the FM signal direct through your antenna wire, its such a boosted signal that even if there is something being transmitted from the outside world on the FM station you select, it overrides that signal. There is no way to get around using the Sirius magnet antenna

OK Sirius receiver is installed I will have better pics soon, it turned out great. 2 questions
1. Is there a direct connect Sirius wire, I don't want to use the lighter adaptor plug, I guess I could cut a splice but I would rather buy one?
2. I have heard lots of different locations to install the antenna, where is the best? I like the idea of behind the real taillight and up just below the top of the rear fascia????
