I have a Navman I can turn on but that’s as far as it will go

If your Navman GPS device has frozen on the main screen, you may be able to resolve the issue by resetting the device. Here are a few steps you can try to reset your Navman GPS device:

1. Press and hold the power button on the device for about 10 seconds until it turns off.
2. Disconnect the device from the power source and remove any batteries or memory cards.
3. Wait for a few minutes, then reinsert the batteries or memory cards and reconnect the device to the power source.
4. Press the power button to turn the device back on.

If the device does not turn on or the issue persists after resetting the device, it is possible that there may be a more serious problem with the device. In this case, you may want to consider seeking assistance from Navman customer support or a professional repair service.
It is also a good idea to regularly update the software and maps on your Navman GPS device to ensure that it is functioning properly and has the most up-to-date information available. You can usually find software updates and map updates on the Navman website or through the manufacturer's support resources.

Unplug Navman USB before reinstalling Navman software.

Contact the maker or Google for this item by model number.

There are 2 small screws at the bottom of the unit, remove these and place a flat screw driver or knife in the joint that runs around the unit and prise apart, being careful how far apart you pull as there are wires attached to both sides, the rest is easy as the battery just pulls out and the new one goes in the same place.

Navman does not power up in my car or scooter ( both have 12v cig lighter sockets.

I have had this problem from time to time with my F20 which I have had since May 2007. The simple solution is to turn it off and then on again and let it go through it's start up sequence. It is far better for this to be done whilst stationary.

my navman f20 has lost its sound

you have a small button on the side of your navman, an ON/OFF button! put it in the OFF state, leave it for a few minutes and then put it back ON and it should solve yourr problem

Goto the navman site 'www.navman.com.au' and download the service pack for navdesk. this will fix the problem

Your Navman is in Demonstration mode and is demonstrating a route that you have set up. It should be flashing SIM alternately with the time taken on the route so far. 
If you don't want the 'Demonstrator' to operate, you can turn it off. See your manual. If you have not got one, you can download it from the Navman site. 
I only have the iCN510 and I have to go to the main Menu screen, tap 'Route Information', then Cancel Route to cancel the current demonstration. 
To turn off Route Demonstrator from Main Menu  Settings  Routing  next screen  Untick 'Demonstrate Route.
