I installed the SkyFi2 system today. Put the antenna up on the roof and guided the wire into the passenger door jamb and into the car. Even know it isn't permanently mounted and running from the internal FM modulator of the SkyFi...I'm pretty pleased with the sound quality and stations.

Also, I drove across the country from Anaheim to Orlando last summer and discovered I really didn't like the selection I had at times. I'll likely be doing the trip again this summer...so XM should be a nice addition!

Thanks for your input everybody.
Once I have it all mounted I'll post a few pictures!
