Nokia 770 Navigation kit question
 

Hi Folks,

I've recently picked up a 770 cheap 2nd hand and am interested in getting the GPS navigation kit. Is it possible to use the 770 and the GPS with the screen turned off? I ride a motorbike so would like to keep the tablet in my pocket and just listen to the voice prompts through my headphones. Turning the screen off would no doubt increase the battery life. Is this possible?

Thanks,
Joe
