I doubt GPS is enabled in this ROM.
The Alltel ROM for PPC6800 Titan is NOT GPS enabled. However, the SPL and radio are "GPS-ready".
All that was needed to enable GPS in the Alltel ROM was to add these 3 files from the Sprint GPS ROM:
- GpsDaemonService.Dll
- gpsid_qct.dll
- qccmquery.dll
So if the ROM isn't GPS enabled, but the radio is GPS-ready, adding those 3 files should do the trick to enable GPS.
