My wife bought it a few months ago on sale from Best Buy and gave it to me for Father's day. I had it activated 3 weeks ago, and it's not working right now. The 8, 3 and display buttons are not working when it DOES power on, but at lunch etc it would not even power on. the FM Modulator in it works sporadically at best. Best Buy isn't willing to do anything, hopefully XM or Audiovox will. Anyone have any experience with this?
