Advertisements Thanks for the help, all. The first thing they did was try to remotely turn it off (which did nothing) then tried to reinitialize - which also did nothing as far as we could tell. I never got bumped to the CC help desk - I can't say I pushed for it this time. I hit resistance when I pushed last time, about a month or more ago, when they wouldn't forward me and it took 2 separate phone calls (each about 90 minutes) before it finally got working. Actually, that's not fair - one rep tried to forward me, but apparently was told to "handle it" by the CC help desk, so alternated on the phone between me and them. @BigBearf: Your item 5 is what happens - except that it resumes the 8-blink cycle after going through the solid green/blinking/off cycle when I reconnect the Tuning Adapter. So...not sure what to say. Reinitializing didn't work, and the TA works fine until it goes offline and into 8 blink mode - at the same time other forum members' do. Hopefully the truck roll will help, although unfortunately it'll just be my tech-naive wife at home.
