So it's back.

After my car sat nav knowing where it was for the last 2.5 years it is now lost again.

In reality my car is travelling daily between home (south of Sheffield) to Scunthorpe.

In the car the sat nav thinks it is somewhere near Burton/Tamworth, and just moves randomly around as I drive.

The driving journal on my phone thinks the car is making a series of journeys back and forth north of Gainsborough.

So here are my questions:

- Why? Software or hardware?
- How the hell does the driving journal think the car is one place and the sat nav think it is somewhere else?
- What would happen if I had a crash and the car summoned the emergency services? Where would they go? Where I was, or Burton, or Gainsborough, or even a 4th location?
- I never use the sat nav so wouldn't really mind, apart from it corrupts the speed limit database so the car gives erroneous speed warnings.......

Any help gratefully received.......
