The receiver for the car charger on the Navman has fallen into the Navman F20; on the last few occasions when I used it the message kept coming up that the battery was very low even though it was -apparently- charging. Presumably it was not charging because the connecting point had become loose/detached within the NavMan itself. Is this repairable at reasonable cost?
I have also had this problem where the connecting part for the charger has fallen into te device itself, I have opened it up and it just needs soldering back into place, if you get anywhere let me know
