My Bose factory unit was lit up this morning but no sound was coming from it. When i got home i checked the fuses in all 3 fuse boxes and they were all good. I then unhooked the battery for 10 minutes and when i hooked the battery back up it wouldn't power up. I then pulled the unit out and checked the connections and re0installed and same issue, no power. I've been searching this forum and Google and seems to be a repeat problem but most posters don't reply with fix. Any recommendations before i take it to an AUdio place?
