The memory card is not the thing at fault ginko, this device has its own internal memory apart from the card.


If it is coming up with an error saying unable to access internal memory, this is a known problem and Navman says that some units are defective and you just have to take it back to where you bought it or give the manufacturer a call and they will take care of this for you easily with no problems and you can then get back to using this.

For support call the number that came with your unit or

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.

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.
