3 times in the last 6 months I've started my car and all of my Sirius presets were gone. The regular radio station presets were there, but the Sirus presets were gone (the Sirius channels still worked when I manually tuned to them). I thought maybe it was because the car had sat for a week without being driven while I was out of town and maybe the battery was low or something, but the other 2 times it happened was between when I got to work and when I left the office at the end of the day. Anyone else have this happen? I called the dealer and they were going to check around, but never heard back from them. Just a bit annoying to have to reprogram them all.
