Reset navman F10 sat nav - GPS

Press and hold the on/off button for ten seconds will re-set the system on the satnav. If the screen freezes after loading the maps then connect the Satnav to a pc via a usb lead and download the latest Service update fom Navman.com. With the Satnav connected to the computer and the download compleated double-click the F10 set-up.Exe and it will update the system on the Satnav. Once complete disconnect the cable and restart the F10. That was the way I sorted mine out after recieving 'little' help from Tech Support from Navman.com. My problem seems to be in the Multi-drop ability of the F10 [program one location and try and add another to plan a route] but I have never got anyhelp from the tech's other than "Buy a Connectivity kit from us and you may be able to use that to fix the problem....". If you get a "Not enough memory to complete update... " message after double clicking the F10 set-up, you will need to go into your F10 Satnav memory and look up some of the saved files from previous routes you have stored in there. I deleated some of these to free memory and it didn't seem to affect the Satnav's programming and allowed the update to complete. My F10 started fine after that. If you need any more help, Navman.com tech support may be able to suggest something....., just don't hold your breath....
