Query: Don't buy this product

I purchased this unit about about a year and a half ago for a family road trip. We were initially pleased with the design of the unit. It worked well and was very versitile. Recently the video part of the unit went dead. Although the sound works, you have nothing but random noise on the screen. We used this product for probably less than 50 hours total. From what I can tell of other online reviews, Audiovox products are very unreliable. I feel a product that costs this much should last longer than a year and a half of very infrequent usage. Stay away from this product.
