Sat Nav loosing itself

[Old Nick]

I have Sept 2016 B9 fitted with the technology pack and I'm finding the the Sat Nav is loosing it's position on occasions. When this happens all navigation stops and it only resets itself after a considerable time. Has anyone else experienced this and if so is there a simple answer?
All help appreciated.

Lots of people looking but no replies as yet! Local dealer (Bedford Audi) aware of the problem but as yet again no answers!

Now sorted by local dealer - Hopefully!
