Navman f-20 cant detect internal memory. i have reset the unit thanks gary

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.

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

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.

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

hi sir,,
may be memory card correpted..

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

Have you tried the reset hole? make sure there is nothing stuck in there that could be pressing on the button. When you press and hold the reset button the screen stays blank.

If you press the reset button does the unit turn on? Mine turns on when I press the reset button even after I turn the battery off then back on.

Hope this suggestion might help you restore functionality.

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.
