Hi all. This is my first post here so sorry I'm hitting you with a question... I've just done a 1000 mile round trip to Paris in my 2014 Elegance estate and in terms of comfort and driveability the car has been great. My problems started as I headed to Dover and the sat nav started to put me about a mile to the west of wherever I was. I assumed this might have been related to the clocks changing so I reset the clock and it seemed to fix it. Once in France the problem began again after running smoothly for a 100 miles or so. I was in a complex junction coming off the A1 in Paris and it suddenly placed the car a few miles away in a field. I had paper maps with me and we used them once we had found somewhere to stop safely but trying to extract yourself from some Parisian housing estate with a road map rather than an a-z isn't easy. After some digging in the manual I got the satellite information up on screen. Basically the car would fire up and recognise 10ish of the available 15 satellites which is fine for a GPS unit. Within 10 minutes it would then drop all the satellites and run on dead reckoning until we went under a toll both. Then it would fail completely, bung me in some field near the last recognised point and not reset. The sat nav worked intermittently for the rest of the trip but was so unreliable we had to use paper maps which is never healthy for a marriage! I know that we all used maps before sat nav but I wouldn't choose to navigate across France with a paper map when there should be a better alternative... I wondered if anyone has any experience of this before I go to the dealer and try to prove to them I have an intermittent fault which is always fun!
