Thanks all for the information. I went ahead and installed xm in my car. It works great. But, my installer put the antenna on top of the trunk (he followed the instruction). I wish, he hid it somewhere inside the car (like back light).. Do you think, I can remove the antenna without damaging the car paint and put it some other place in the car?
I also noticed that the song title/artist information is incomplete (shows only 11 characters).. I think, this is bad... Why couldn't they make it so it displays a complete information? Do you think, this is a XM receiver problem or a Mark Levinson audio display unit issue?
