If you want to run Navit on your Sony nav-u device, do the following:

  1. Download the following programs:
    • Navit [1]
    • Sirftech [2]
    • Mortscript [3]
    • Tooldevice.exe (this one you will have to find somewhere on the web. You can also write me a message, and I will send it to you)
  2. Hard-reset your device (reset button on bottom)to gain write-access.
  3. Connect your nav-u device to your computer via Activesync and USB and start it up.
  4. After connecting clik on "explore" in ActiveSync window (alternatively you can go to "mobile device" in Explorer).
  5. Browse to "Mounted Volume"
  6. Create Folder "Navit" and copy contents of navit-current.zip into that folder
  7. Copy sirftech.exe into "Mounted Volume"
  8. Copy contents of mortscript.zip/bin/PPC into "Mounted Volume - Sony - nav-u"
  9. Copy Tooldevice.exe into "Mounted Volume\Sony\nav-u\
  10. Rename nav-u.exe to nav-u-original.exe (or any other name)
  11. Rename Autorun.exe to nav-u.exe
  12. create a text file named nav-u.mscr with the following content:

13. Replace the content of "Mounted Volume\Navit\navit.xml" with the following:

Disconnect your device from the computer, reset it again and start it up.

System Settings will show up, where you can set power options, sound etc. Exit systemsettings

Sirftech will open, where you will have to set your gps chip to NMEA mode: Goto "Com" Do NOT click "find port and baudrate"! select your gps port from the dropdown list try to open port with different baudrates, starting with 4800 (and, if that does not work, with 57600 baud). At the right baudrate, it will show either NMEA or SIRF mode and the incoming data.

If the port is set to NMEA, 4800 baud, everything's fine and you can close the port and exit the program.

If the port is set to SIRF, 57600 baud, then leave the port open, click ok and open the sirf menu. The last item on that menu lets you change the settings to NMEA mode. Select 4800 baud, click set and =baudrate. Go back to "Com". Now it should show nmea mode working with 4800 baud.

Exit sirftech. Navit should show up. Have fun!

Note: normally the gps chip stays set in NMEA mode even after a reset, but if you reset twice, the chip is reset to SIRF mode and you have to switch it to NMEA mode again.
