I installed the SIRIUS SIR-GM1. Purchased it on the Internet. If you use this unit, the wiring harness has 3 plugs, you use 2 of the 3, tape over the third. It plugs into the back of the radio on the opposite side from the OEM radio plug. It also requires that you cut a small piece of plastic so that the "new" plug will fit when you slide the radio back in.
Of course all of this occurs after you remove the front of the dash, which requires that you either pull it over the air bag, or remove the airbag. I recommend that you use Mike in AZ's method and remove the airbag. It is vexing to remove, but after you put it back in, you do not put the top studs back in, only the two bottom, which are easy, so that you can remove easily the next time. I did it this way because I did not want to cut on the dash tabs, or possibly damage the plastic of the dash, very hard to purchase.
If after all of this, you still want to put one in, go the "SEARCH" on this forum, type in Sirus Install and you will find Threads like this:

Scooter,
The OEM 24 pin connector stays in the radio, one end of the "T Harness" goes to the 12 pin connection on the bottom left side of the back of the radio, one end goes to the GM-1, and the the grey?end of the "T Harness" is unused,(I just taped the end of the connector). You will have to cut the plastic behind the radio to allow the 12 pin connector room to slide the radio in. I installed the GM-1 Module by just duct taping (of course) it to the bracket just above the radio.
The yellow wire on the "T Harness is connected to a battery source. If you don't have this connected to the battery the radio may NOT retain the button preset settings for your favorite Sirius stations.
All of the steering wheel controls work. You will have AM, FM1, FM2, SR1,SR2 by tapping the BAND Button.
Some of the guys have installed the antenna on the bracket in the center of the dash area just before the windshield so that is not visible under the top dash, and report good reception. I was a little leery of that, some have reported that reception will vary according to where you are, some parts of the US get better reception with the placement because of the angle to the satellite. The antenna is a mini, I put mine beside the vent on the right side of center just behind the windshield trim, (see picture)
