what brand name is it ? if it is Garmin then there should be a button on the back of it or bottom it is small just hold it for a few seconds then it should reset it all. hope it works

Delete the app and reinstall it via iTunes.
If that doesn't work, you might want to consider restoring your iPhone via iTunes, then reinstalling Navigon. Hope that helps.

Please remove the battery for a minute or so. If the problem still persists then have the firmware reinstalled as it has got corrupted.

there is a reset hole somewhere on there that you could fit a paperclip in, click on that for 5 seconds and it will reset your device for you

Well after many emails to Navigon I got the fix for my 2000s What you have to do is download the 1.2 version software for the 5100 install it on a 2GB micro SD Card. Put it in the slot and turn it on. You will have to regester as if you have a 5100 but it will work. The reason you have to use a 2GB card is the maps are to large to go on the internal memory.

Make sure the sd card is seated properly.

Sounds as if the system software that runs the GPS has been corrupted. Your device should have come with a CD that has software that can be reloaded or a utility that can be installed on the PC that connects to the navigon website to download and install the software for you.

Might want to start with that.
Hope this helps

The software on the micro sd card is corrupted. You need to get a new software image

2 things that might help...use a paperclip and press the reset button (small hole on side, you'll feel a click) hold it for 5 seconds. THEN hold down the power on button for over 10 secs (keep holding while it shows version number) and it will perform a factory reset. You will possibly lose any settings and addresses, but better that than a locked GPS unit.
