Query: Units died. VERY DISSAPOINTING - Shame on Audiovox!

We bought these units during the 2008 holidays on the recommendation of a friend. The kids were sooo excited. The units worked well at first, although the sound was never great. We used them three times during the past 5 months for car trips; and the last time we tried to use them (returning from our last trip) they just died. We tried replacing the fuse to the car adapter which we read on the net was a common problem with the units, but to no avail. I wish I had read these reviews before I made the decision to spend $200. We feel like we've been robbed.
