This is a fault with the internal memory chip failing. It can not be fixed and requires the unit to be sent to Navman and the chip replaced.

Return your GPS to the place of purchase and they will complete the return for you if you've had it less than a year. You will need a repair ref number from Navman before sending it back.
This would cost you if the items out of waranty.

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

I bought the same, but managed to download the manual from navman. Try again friend.

Probably the plug on the navman has suffered what we call dry solder joints from inserting and pulling out the charger you need a tech to fix it. soldering is nesessary shouldnt be too expensive I fixed mine its about half an hours work if not too damaged inside

Hi,

Heres 2 solutions.

1:- try a hard reset.
2:- try starting without any memory card in the device.

Mike @ Compurepair.

undo the two black screws in the base an gently prize it apart.

Normally the sd card holds the programme and the maps so the satnav will not run without it. If it is already in place, take it out, wipe over the contacts with a dry cloth and reinsert it. If there is no sd card then it will not work-it has no programme.

I have a navman f20 sd card with US maps would be glad to make you a copy of it. [email protected]

The internal memory on the F20 is actually an mini SD card inside the unit and this fault is caused if the card can't be read. This is mostly likely because there is a poor connection to the card. To cure the problem:
1) Remove the two screws on the bottom of the unit.
2) Divide the two halves of the case. Its best to do this by using your finger nails or a plastic lever. If you use a screwdriver or something similar you will most likely damage the case. Take care when you finally are able to divide the two halves of the case not to strain the cables connecting the battery and loudspeaker.
3) You should be able to see the SD card in its holder on the circuit board. To remove the SD card pull the top edge away from the board and the top half of the holder should hinge outwards. Don't try to pull the card out as you would do from a normal external SD slot.
4) Examine the terminals for any corrosion or contamination. In most cases just removing and re-inserting the card does the trick. You can safely switch the F20 on with the case still open, but don't attempt to insert or remove the SD card with the F20 turned on as this may damage the circuitry.
5) If this doesn't solve the problem the card itself may be corrupted. You can check this by inserting it in a computer card reader to see if it can be read that way.
