I tried to find some info on the cell phone charger in the Owner's Manual and Navigation Manual but couldn't. I know that if I store my phone down there and have it switched on that it will charge the phone while I am driving. I often drive without my phone and can't really see the tiny light at the switch that shows it is on or off. My question is: Can I just keep it on all the time and not worry about turning it on when the phone is there and off when it is not? Ray
