Yes, I've had the problem, too. We were on an all-day trip, and I thought I was fine as long as my phone was plugged in. I totally ran out of charge.
I was using the USB cord along with a little adapter for the cigarette lighter of the car. I'm thinking that the adapter did supply enough power. Upon studying the product descriptions, I found that there are differences in the amount of power supplied by different car adapters. So, I ordered a new one that should supply more power. I haven't tried it, yet, though.
What car charger were you using? Has anyone found one that works when the GPS is running?
