My S2 installation is not going well, and i think I may have decided to get a different radio for my car anyway. 1. With the Stiletto 2, can you change channels from say channel 7 to channel 8 without going back into the menu? I like how on my sportster I can go from channel 7 to 8 to 9, etc... 2. What is the best Sirius radio to get for my car now? I really like the way the Sportster works and the large display. I do nto really need anything fancy, the basic has worked well all this time. Thanks for any suggestions.
