We were travelling back from Angers for the second time in a month.
At around 35km from home, perhaps around Doué-la-Fontaine, the GPS started playing up and quickly stopped working. I had to pull in to a layby and remove the SD card, reinsert it and satart the car. It then worked fine.
The strange thing is that exactly same thing happened last time we drove that route.
Any speculation as to what’s going on? It’s the only time and location it has happened.
As you have now had 2 strange experiences (GPS and Shutter) I suggest you approach the future with caution.. since things usually come in three’s 
No, that was last week.
GPS black spot, any sensitive military stuff near by? I had a GPS blackout near a military base .
that sort of thing would certainly make sense…
There are military areas around there but mostly further east - lots of “no fly” zones for drones, for example:
And EDF’s nuclear power station at Chinon.
But you can get GPS dropouts quite randomly - I’ve had them when travelling on the A28 and A88 autoroutes, for example.
Madame’s thought was something military. Next time it happens, I’ll try to identify the location better.
On my map screenshot the orange dot is Doué-la-Fontaine.
The red and yellow striped area is Saumur aerodrome. The red blob to the east of it is I think a military training area - I vaguely remember seeing warning signs when riding up the D147 from Loudun to Fontevraud. There is an École Militaire at Saumur I think.
The larger red blob further east is EDF Chinon Controlled Nuclear Bangs Facility between the Vienne and Loire rivers.
Yes, there’s a lot of Army forest around Fontevraud. Sometimes the roads are closed because they’re using live rounds 
My geography is poor, but I think you may have hit on the reason.
Can confirm. We stayed for a month in the area at an Airbnb 3 years ago, at Savigny-en-Veron. Do not recall any issues using Google maps though. But there’was not much of a war going on then either.
If removing the sd card and restarting cured the problem it would seem unlikely to me to be anything to do with the military.
There’s a fairly well known fault across a range of VAG vehicles where the GPS seems to lose track of where it is. Certainly my Skoda Karoq used to do it and I’m fairly sure it would happen at the same places during journeys. It would manifest itself on the car’s sat nav as well as Google Maps and Waze.
Might be relevant but I never bothered to look into it any further.
That might be it, @JohnH .
It happened once in the UK, but twice on the same journey in France.
Glad I’m not being jammed.
