Question about Navman F20 GPS Receiver
There are 2 small screws at the bottom of the unit, remove these and place a flat screw driver or knife in the joint that runs around the unit and prise apart, being careful how far apart you pull as there are wires attached to both sides, the rest is easy as the battery just pulls out and the new one goes in the same place.

Undo 4 screws. 2 under GPS reciever flap and two underneath black screw caps (just pull these off).
Then slide something thing under edge and pull quite sharply. (its clipped on so you need to give it a tidy pull)

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
