Going back to the car charger debate, for those who want to use the nav and other features while pluged in and not kill their battery. I got the HTC "Charge Now" warning at 8:00 this evening, I was about 1.5 hrs away from home so I plugged into the car charger.
The charger is the Verizon model MICUSBVPC; I tried looking on the VZW web page but it is not listed, I got mine at a VZW Corporate Store.
During the ride home, I used GPS nav, BT speaker, made 4 calls and sensorly was running in the background. When I got home, the meter was at 50%.
Just thought I'd share my experience .
