I've been using the iPAQ 6915 for sometime, but can't seem to get reliability from the GPS. It starts to find satellites and then stops responding. The ROM version is 0.82NA.00 ENG and the GPS Driver version is 1.00.00 Firmware Version is 4.1099.123.0 and software version is 0.12.2139.0. In checking HP's site there isn't any newer drivers or newer BIOS update for the PDA. Could Global Locate offer any updated drivers? Any suggestions on the settings for the GPS Program Port, Hardware Port, and Baud Rate? Again the HP manual isn't specific on these settings either. I would appreciate any help you could offer. Thanks.
