I picked up my car last Wednesday (Dang do I love this car). I didn't have to call anyone, the XM was up and running. Not sure if 06's came with this or not.

Nope... the XM is only on '07s. The '06 models were "XM-Ready", a poorly named item... meaning you only had to pay $800 to install the additional hardware to actually receive the XM signals. I chose to just transfer my old XM roady device into my '06. It plugs into the aux port and works just fine.

Frankly, I'm getting frustrated with XM since they've decided to add commercials to many of the music stations. Seems very unfair... you pay for the hardware when they advertise "no commercials on all music stations", then a year later they change the policy. If I'm paying for radio, I'm doing it because I DON'T want to hear ads. Grrrrrrr!
