Everytime I travel up (or down) the A417 my SatNav seems to think I have suddenly driven across a field to drive on a parallel minor road. It always happens at the same place, north of Cirencester where there is a viaduct. I'm convinced the road mapping is incorrect.
Anyone else driven this stretch and had the same effect?

My friend doesn't have SatNav but did try to drive across a field near the A417 - I've always thought of Northleach as the twilight zone.

No, but the A41 extension from Tring to Aylesbury causes the same behaviour with my TT3 set up. All sorts of spurious commands are given in the middle of a 'field'!
In my case it is because the road extension has been built within the last year, and Tele Atlas (whom TomTom and most other sat nav developers purchase their mapping from) haven't provided an update, yet.
I have, however, found one genuine mapping error (actually a street name smelling pistake), and on reporting it to Tom Tom via their website, I received a fast acknowledgement that Tele Atlas had been informed.
May be worth you doing likewise with your error to whoever manufactured your SatNav software?

Seen similar occurances on other roads sometimes, but not travelled on that particular stretch.
Strangest thing I've seen is that, when I'm leaving the car park at the University of Nottingham (which I visit occasionally on business) I cannot get the sat nav to register and pick up enough satellites to pinpoint my position - it keeps resetting itself constantly until I'm back on the A52.
This is the only location I've ever been to that gives me this problem.
I've often thought that Nottingham was on another planet!!.

my sat nav always thought the A14 went through the battel of naseby battle site.

I wonder if the maps in your GPS have the location of the old A417 in them (which is now, in places a parallel minor road), not the replacement dual carriageway.
My handheld GPS doesn't follow the A417 well, but it exhibits similar 'diversions' elsewhere. It has fairly basic mapping, so I'd always assumed that was the problem.

I notice this a lot all over the country. I've driven through buildings in Bath with my lorry!!
I use a Garmin GPS and a laptop with autoroute 2005, not sure which one is at fault.

I have found even the latest maps to be years out of date, I would never waste money on genuine ones to find they are just like the one I already have. I get the next version as soon as it comes out, yet junctions built a few years ago are still not on. This is with both Navteq and Teleatlas, overall, I found Bavteq better so stick to them.
