Navman f20 won't work, just displaying red writing when i turn it on

You can get a user manual for the Navman F20 at Navman F20 Manuals

Does that help or do you want to know something specific?

The battery is defective or your charger is not working. Most likely it is the battery but the charger is a possible until checked. You may want to find a gps shop and find out if they can get a battery.You can also contact Navman and talk to support about sending it in to them for repair. The battery should be about $20 plus labour to install.

Hi,
Not much to do here I'm afraid. a repair is needed. If your device is not under warranty anymore, you can get in touch with Navman / Mio, they have a trade in offer towards a new Mio device

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.

Hi,

I think that the micro SD card inside the GPS is not in the good position, it is necessary to remove the grey sticker on the rear of the GPS and open the hood to access the SD card and then you can plug it in good position.

Try cleaning the contacts on your b2 with a contact cleaner, could be that simple.

the speaker is gone replace it with ant small speaker and it will work again
