So i took the family out for the day to a location a hour away and had to use the sat nav. It got us there fine. Problem is on way home it was stuck at the location! I entered the postcode to go home. It said route being calculated and i selected the first option of distance. Only to notice it was not guiding me! Managed to get home by followi g sign posts and did the 3 button rest and also the MMI sat nav reset but still it thinks im at that location even tho im at home! Its stressing me right out now as i jave no clue about what to do and how to fix. Please help.

The car sometimes cannot catch fire, even on the road will fire, need to wait for about two minutes before they can play on fire, what reason is this?
