Hi Bob,
Installation of the XM module and antenna was pretty simple, but did require the removal of the LH Middle Side Panel (where you check oil), LH Wind Deflector, LH Mirror, LH Service Panel, LH Top Side Panel, LH Rear Side Panel, Rear Panel (horseshoe shaped panel that wraps around rear of RT), Battery Access Panel and the LH Rear Speaker Module. Whew... am tired already!!
Having taken all that off, you drill a couple of holes (using template provided) just above rear compartment (in the area just forward of rear compartment) for the antenna bracket to be mounted with push pins. Then you route the antenna lead down to the forward area of the LH saddle bag storage compartment where the XM Module is installed. The XM module plugs into the Entertainment Harness for power and audio control.
PLEASE NOTE: This was as "simple" as described above ONLY because the Entertainment Harness was already installed (from the CB installation I did last year).
To install that Entertainment Harness, you'd have to remove (in addition to what I described above), the RH compliment of parts mentioned above, along with the seat and then the whole saddle bag / rear compartment module (basically the whole back end of the machine). I used several straps and suspended it from my garage door track and garage ceiling, and it was a full day's effort! :gaah:
So, since you're "allergic" - you'll want your dealer to do this, and they'll charge you 3-4 hours (just guessing - check with them) of labor.
Hope this was helpful,
Bill
