Query: Garmin nuvi 350

I purchased this item as a gift for my husband and it worked great for a few days. In the middle of a trip the Garmin just shut down and stopped working. Although we plugged in the battery charger, the navigator never turned on again. I am now waiting for a replacement, hoping that the first was simply defective. It was quite disappointing to be in the middle of a trip and lose your navigation system. The charger was on, but the Garmin never started up again.
