Dec 2014 Mk4 1.6 Dti Mondeo. Yesterday I drove on a motorway in the rain to the supermarket and all was well, however when I got back into the car the Navigation had a blue screen and the little red pointer but no map, when I looked at the number of satellites it showed zero, and the message came up, something along the lines of make sure you are on a digitised road. I tried restarting both it and the engine and made sure I was on a "digitised road" but, still navigation not working. In addition the battery warning light came on with the message "low Battery", so two possibly associated electrical problems. From the information I have seen on this and other sites, it appears to point towards damp getting into the electrics. However, this morning the navigation and the battery warning have both resolved themselves, so it really does point at water getting into the circuits, I have looked under the bonnet but I cannot see any water around the fuses, etc,
Nan anyone tell me where is the most likely place where water getting in could cause the problems please? Thanks in advance.
