Initially, I too had the same exact problem where I pressed the AM/Sat button and only the AM buttons would cycle, and then sat1/sat2/sat3 displayed but only played a total of 12 channels.
I took it to lexus (6 months later) and found that it was never activated and the blonde in me (i have no blond streaks btw) thought it was due to the satellite signal not being good.
Sirius is horrible! They put the black triangular receiver on the passenger side on the front glass of the vehicle. The connection is not solid and almost always loses signal whether its a clear sky or cloudy one.
I found a lexus dealership with a coupon for installation, maybe your local lexus dealer can match or beat it.
