    I've managed to speak to technical support at Navman and they advise that the system requires a new motherboard. Apparently its a recognised problem with the F40. So we're just going to return to the vendor for a full refund. They would replace it but I don't think there's any point as the chances it the problem will simply recur with the new one.

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

I reset my F series,now it tells me


unfortunately, per C-Net's review page at "http://www.cnet.com.au/navman-f20-339272352.htm#comments" there may not be any software available as that these units are now "obsolete". but there does not seem to be any "free" software at all.

hold it! just found the software page from the company at "http://www.navmansupport.com.au/All%20Navman%20FAQs/Software/F%20Series.htm" for this unit. could not find a "direct" link to the download, but you may have better luck.

it would seem that there are drivers in windows for this ( according to what I saw on the site)

on some further searching, it seems that there is a sd card in the side that may be loose, check that out, too!

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

Our copier doesn't copy and shows error message "unable to print..." we want to get it fixed, please help


The graphics is not initialized
because the graphics memory
was not reserved. This error
rarely occurs unless the printer
detects the memory failure.
Please note that
“RPCS”(RICOH printer language)
is the same worldwide
and does not need to be translated
Replace the installed memory.
Turn the power off, and then on. If the
message appears again, contact your
sales or service representative.

Erreur f20


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.

F20 navman error


You need to remove the 2 screews from the bottom and then gentley prize the unit apart from teh bottom using a blunt broad knife will help if you cant have the plastic case splitting tools which are used in the trade,

then once apart the same side where the power button is you will see a microsd card its the same as in a mobile phone just pull it down from the top (its hinged at the bottom) then make sure the card is in correctley and then close it back and test (b4 putting the case back on) that will fix it we ahve a lot of these coming in and its where its been dropped etc and jumps out thats it

NAVMAN F20 failure - unable to detect internal memory


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.
