My navman MY75T screen is stuck on the icon of the connection between the unit and the pc after disconnection and after reset

Hold down the on button until the screen goes black. wait two min, then turn it back on. If that doesn't work, try connecting your device to your computer and go online to the manufacture website. Most have a way to check your device and fix/update it.

The F20 Desktop Software and Service pack on the CD's from navman do not work, as you have seen. The solution is to go to the navman website and download this Service Pack

Be sure your f20 is connected to the USB cable and turned on displaying the USB Connection screen. Leave it on during the entire process.

Once downloaded, run this self extracting file and let it install automatically. After it is installed and ran.....you will see the same error again of failure to connect.

At this point you must reinstall the driver manually. Right click on your "My Computer icon, Select Devices, then properties on the navman. You should see a yellow "?" next to a statement "Unknown Device" in the USB devices. Click on the "Reinstall Driver" and select a specific location or the Have Disk button. The USB driver is now located in C:\program files\Navman\f20servicepack\USB directory.

You should get a button that now says Okay at the bottom, click onto it and allow the MS program to update the drivers. You should see the device screen change and say "This device is operating properly". You can then close the windows and run the F20 desktop program. It should connect then.

try pairing the phones with a hands free device, if they pair and work, the problem is the gps, also remember that most phones can only pair with one bluetooth device at a time , so if you pair to the gps then pair to a handsfree device, the gps connection will be lost .

1. Connect Navman GPS to PC via mini-USB cable.

2. Go to 'Start'

3. Go to 'My Computer'

4. Open the Navman Unit

5. Open the 'Navman' folder

6. Open the 'Database' folder

7. Delete the following file only - 'dababase.db'

8. Close the folders

9. Disconnect the mini-USB cable then restart the Navman GPS by sliding the switch to 'Restart' then back to 'On' after 10 seconds.

The database.db file will be generated automatically once the folder is closed.

I had this problem when I completely deleted the Backup folder from \My Flash Disk.

Restoring the backup folder allowed the 520 to operate properly again.

It is possible that you have a corrupted APPStartupSec.exe application. Without this file working it appears that the NAVMAN waits in USB mode for ever!

Hope this helps.

Hold down on/off button till screen clears,this should reset navman F10 .Turn back on and it should be working normally.this worked on mine.

i was in car,using navmanf10, went blank and a comput screen connect to unit appeared, cannot do anything with it
