When I use RunGps on my HTC Touch Diamond, the battery will be empty after max 4,5 hours. So I tried to connect an external GPS to the Touch Diamond. I followed the instructions on the rungps-manual, and everything worked fine, except , the battery was again empty after 4,5 hours. I assume the internal GPS is stiil switched on, dispite of the connected external GPS. Is there a way to force to switch off the internal GPS? I have Windows Mobile 6 on the Touch Diamond.
