I am a new droid owner and new to anything android. Anyway, I had a play with the GPS navigation today. I plugged the phone into my charger, selected a destination and chose navigate. The thing works incredible, but here is the problem. For one stretch I had to drive straight on the same road for about 18 miles. The phones screen locked about a minute into the trip. It seems like soon as the app stopped talking to me the screen slept after the 1 minutes time I have set. Now I was NOT using car home, I just opened google maps and went from there. If I use car home will it ensure my screen stays on? I can not imagine this is how it was designed to work.
