Can anyone assist me please, just purchased the A5, the Nav is stuck on a route from previous owner, unfortunately did not realise till purchased. The Nav allows me to enter a new destination but then defaults to the same old route - so its useless. The car has plenty of Audi history, and works in every other respect, but i cannot see any Nav references. Does it do this as the Nav is not updated, or is something broken ? If so whats the alternative to handing my bank account to the main dealer...thanks in advance for any help
