dna is off the scale
Default

I was driving last night doing some last minute xmas shopping when all of a suddeen the speakers died? The radio was on, all the buttons worked, I could change stations, but no sound. I even tried CD and even tried the On Star - still no sound at all. I parked her at the mall for an hour and when I returned all was fine again?

Me H2 is still under factory warranty - should I take her to the shop for this? What could cause all the speakers to suddenly die? Could the Bose amp be going?

Thanks

Sounds like your H2 was retaliating for having to go to the mall!

I would certainly take it to the shop, especially if it is still under warranty. But, don't expect it to replicate that problem while it is there! Nothing is EVER wrong while my truck is in the shop!

I just had that happen to me for the first time last week. I have about 38000 miles on my "03 and it has never happened before, but it was just as you described. I stopped at the store for 10 minutes, thinking about when I was going to have time to take it in to the dealer. I came back out, started her up, and all was working fine again. No recurrence in about 6 days so far. Hmmmm.

I'm not sure about a remote for the wife but I'm pretty sure she has one for me implanted in her eye.

Those are not tramp stamps. They're bionic, heat seeking, infrared, death beam machines.

Mine has done the same thing lately. I just assumed it was an XM thing because it happens only when listening to XM. I am on XM 95% of the time though?
