As a side note, if you have XM you can use the crappy antenna clip on thing for FM modulation, but you can also get this FM DIRECT adaptor that goes in line with the antenna. When your XM unit it turned on, the FM DIRECT turns off every frequency except the one that it is broadcasting on, that way there is no interference from the outside. I have installed lots of XM radios, and the FM DIRECT is the best option besides using an AUX input (which most factory radios dont have)
Heres a break down in order of worst to best performance.
1. FM modulation, run a long wire to wrap around antenna, lots of noise, limited success, free
2. FM DIRECT, put a little box in line with the antenna cable, as good as your FM tuner will allow at best, $40-$70
3. Tape adaptor, Cassette with wire that plugs into your XM, tape quality is better than FM, usually included with kit, 5-10 bucks anywhere else.
4. AUX input, Plug a 3.5mm male-to-male headphone cable from the XM to your auxillary input, best possible sound quality, limited applications, $5-$10
