I have it and i really enjoy it, but i would say only get it if you can comfortably spend the extra money it takes to buy it. I barely notice the $10 a month i pay for it, but the installation is expensive, especially that alpine tuner. With the mp3 feature you can get as much music for cheaper, but on xm i really like the talk channels, sports, news, comedy (funny as hell) Again, i recommend it if the installation price is not so much that it really severely cuts into your budget, it is nice but it is not as essential as a great overall system.
