F20 navman error

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

Remove memory and put it back, if it still does not work memory is probably faulty.

This is not an uncommon error and is mostly referred back to Nab=vman for repair

Other than sending it to Navman you can...Open up the unit (this voids any and all warranties you may still have and if you go with this option forget about contacting Navman). F20's internal flash is just a hidden micro SD card. If you don't have it already, you'll need to get a cheap micro SD card adapter -- with it you will be able to read the card with any card reader. You could then scan card for errors and look for log files that could provide more information on what went wrong with your unit.
Please rate my help++++Thans for using FIXYA

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.

hi sir,,
may be memory card correpted..

Looking for same solution,,, any feedback yet...!!??

I have a F20 here I am currently tring to fix.

The error comes from the internal memory card being faulty.
It is only a micro SD car.

It may be totally usesless, or need re-programming via the USB port.

You can download the firmware, and it fixes a working MicroSD card.

If your card is damaged, then you will have to replace it, and strip the F20 down to do so.
Then you can upload the firmware.

I warn you, though.
Stripping it down is a bit tricky.
I replaced this F20 memory card, and put on the firmware, but have a new error, that it cant find any maps installed.

Hope this helped you

Change bad internal MMC Card for a new one, connect via USB to PC , run f20servicepack1.exe. Don't forget to install Navman's USB drivers ( c:\program files\navman\f20 service pack\USB\ .

go to the other receiver prob to get clue

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.
