I have had this problem from time to time with my F20 which I have had since May 2007. The simple solution is to turn it off and then on again and let it go through it's start up sequence. It is far better for this to be done whilst stationary.

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 wont turn on says F20 ERROR UNABLE TO DETECT INTERNAL MEMORY

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

Application error.

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.

Error message on Navman Navman F Series Failure Unable to detect internal memory. Please return the unit to dealer. Can anyone help?

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
