I have purchased a Sportster 5 from Sirius about a year ago. I have been moving it from car to car and it has never been dropped but recently I lost all of my settings (presets, artists, songs, and display settings) as well as the unit shuts off by itself while I am driving. Has anyone else experienced this problem? I have a lifetime subscription and was wondering what my options are. I don't want to purchase another unit (which will bring me down to 2 more changes before I have to purchase another lifetime sub) but I don't think I will be able to send it in for them to repair it. Thanks to everyone for taking the time to read this.
