I just bought a 2007 328i hardtop convertible. I have activated Siruis XM, and it appears to be working. I have the premium radio system in the car. When I click the arrow buttons on either side of the M button, the channels go up and down as expected. When I use the arrows on the steering column, on the first click, I get a "please call Sirius XM to subscribe" message, and the second click changes the channel. Every other click gives the "subscribe" message. When I use the radio's right button and try to turn it to scroll through the channels, all I get is a "subscribe" message and nothing happens. Do I REALLY have to click these channels one by one without being able to use the button to quickly scroll? I searched the Interwebs, but all I could find were people trying to add a satellite radio after the fact. I have already tried the refresh signal option from Sirius.

I hope someone here can help. This is my first BMW and my very first post!
