GPS problems with HTC touch Pro

The GPS unit isn’t working flawlessly on the  HTC Touch Pro.  I don’t know if the same problems exist with the HTC diamond, as it’s the same hardware.  As far as I know there are 3 possible solutions

  • Wait for HTC to fix the problem
  • flash your rom to ROMeOS 1.0.5, (or later) which has some GPS fixes

    A. With Advanced config 3.2…ol-32-cab.html

    1. disable A-GPS
    2. disable GPS logging
    3. logfile name must be empty
    4. old logfile name must be empty
    5. maximum size of logfile must be 0
    6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt

    7. it seems that if TomTom is installed on a fast microSD decrease the lag(have to test to be sure)

    With those changes car usage will be quite perfect

    B. Then edit registry with TotalCommander

    Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\

    – Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
    – Drivers\InputBufferSize -> 512 (default is 4096)
    – Drivers\OutputBufferSize -> 512 (default is 4096)
    – Drivers\SleepOnNoData -> 100 (default is 1000)
    – Multiplexer\MaxBufferSize -> 512 (by default not present, you have to create it)
