Strange Sat Nav

[Reece.Haswell]

Hi guys Ive had my GS300 Navigator (V plate) for a few months now and loving it, well all apart from the constant visits to the petrol station!

Anyway my sat nav and on board screen seems to be going a bit..well..strange...it started a few weeks ago by wiping all saved data like mpg and average mpg since each petrol fill up, then it changed my saved infor like mpg and english language to km and german! then everytime I started the car in the morning the sat nav thought I was in London (I think where the car was bought) eventually it would catch up but occasionally it would also lock me out of the menu so I couldnt change it! its fine today but may go again tomorrow! Has this happened to anyone else? IF so how the hell do you fix it lol

Cheers guys

Reece
