I had the AVN 5435 Installed the other day at my local Eclipse dealer, along with the Eclipse satellite tuner. Everything works great, and I'm VERY happy with the purchase. Although the Sirius doesn't sound AS good a CD in the unit, the main difference that I notice is that the Sirius has to be turned up higher volume wise than the CD. However, I'm very happy with the sound overall as it is as close to CD quality as you can get, and MUCH more clear than the FM Radio. But I have one question about the Sat Tuner for those of you who have installed it as well. Is there any way to program your favorite Sirius channels into the various bands? I have found how to change them, by changing to a desired channel and then pushing down on the button that I want it saved on. However, every time I turn the car off and come back the next time that I drive, the buttons revert back to the Default Channels 1-6. I cant seem to get then to stay. Is there any special way to get the AVN to remember the channels that I have programmed? Any help would be wonderful, and much appreciated....
