Sat Nav RNS-e

[Tabletski]

Hi folks,
I have a small issue with the sat nav, I forgot my phone today and remembered the car has sat nav built in, rns-e DVD version. Started it up only to find it is about 10 miles off in start location and route. I remember playing with it when I got the car and it correctly found my home address and led me off from the dealers to my house, so I know it was working properly.

returned home out with PC and searched the forum for sat-nav issues, there are plenty of threads with issues and steps.

I have rebooted using the Radio-Setup button press without any change. I have reset the settings from the menu but all that did was turn the volume up.
The GPS aerial must be working as sat-nav starts up in my area. DVD looks newish as is dated 2012.

i found this site after posting, may be useful for reference . http://www.carsnavigation.com/audi-r...avigation-faq/

Anyone seen anything similar? Or ideas on how to proceed?
