SIR GM1

[mrmayhem]

Here's what i did for the antenna.. On the passenger side roof - (front).. the outside amber marker.. take out the one screw and move the light to the side. Look where the light wires go.. a nice black grommet. Pull the grommet out (comes out very easy). From the outside.. feed the sirius antenna into the hole.
Now take off the pass side windshield pillar (done by pulling the two caps out from the handle). Feed the antenna wire from the roof.. down the pillar and into the side of the pass dash (that comes off too). Thats it.

For power.. on the pass side dash.. the panel pops off.. there was two factory wire taps going to nothing. I hooked into that.. and bolted onto a nearby ground.
Sirgm1 was zip tied up inside the dash area.. as the T harness was so dang short.. I was limited on how far I could route it.

Oh.. sorry.. XM and Sirius antennas are not compatable.

if you look, you can see the connector on the other side of the radio

That's where I was able to put the Sirius tuner.

Wrong. Sorry. We mix and match all the time and never have any issues whatsoever. Just did a Toyota oem sirius setup and they forgot the antenna so we used a Terk XM Micro and it worked like a champ. I have used the oem xm antenna with sirius tuners in many many gm installations.

interesting.. crutchfield advised they are not interchangeable.. maybe they just don't know.
