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.

Ariel base on the roof is where you want to be looking, it seems to be a common issue with some of the GPS Ariel bases unfortunately the only cure would be to get a new base as this is where the GPS receiver is housed

Good luck

On a 2014 mondeo, it won't have a roof mounted aerial. Its on the windscreen behind the rain sensor cover.

If it came up with "low battery" and the engine was off, That's quite common and probably nothing to worry about. The battery monitoring is very sensitive. its possible your battery is on its way out, but unless it starts happening every day, I would ignore it. Hopefully the sat nav problem was just a blip

Thank you both for your replies, and yes, there is no external aerial on these later models, so there must be another reason for the navigation problem, I need to do a drive in rain and see if it happens again.  Thanks for putting my mind at rest on the low battery warming, it was with the ignition on but the engine off.  Thanks to you both for taking the time to reply, much appreciated.

Hi, thanks for your reply, yes I am on digitised roads, if I am not on a digitised road the map still shows on the screen, the difference with the problem I had is that the screen was totally blue with just the red pointer, just like the dreaded screen of death you get on a computer.

playing with the gps solved this problem but now and again it still does this

Thanks for that, when you say you play with the GPS, what do you actually do please that brings it to life?  When mine went off I did turn it and the engine on and off several times, but without any result.

I had fitted my stereo myself so the gps I have sitting on the dash near the passenger side

I was going to put it in the pillar out of the way glad I didn't

just moving this slightly brings back the sats (as in info it states zero)and also bringing the screen back why this does this I don't know 

 apollogary says yours is behind the rain sensor so worth having a look and see if you can move it and also making sure the connection behind your stereo is secure
