Sorry if this has already been answered - but how can I keep the screen from timing out if I have the Droid plugged into a power source? I have it mounted to my motorcycle and am using the cig lighter to power the Droid and want to use it as a GPS for driving instructions, etc. and it times out and goes to sleep after 30 Min. I have it mounted in a waterproof case and I can not easily wake it up. Surely there is a way to keep it from powering down if I have it attached to a power source? Thanks for you help!!
