I've just bought a 2008 A4 Avant Sline with sat nav and i have to say my TomTom is far better. I have tried two addresses in the last couple of days and neither are on the map. When i bought the car the salesman was giving me the demo and tried my home post code which didn't come up either so he says my address must be too new....Yeah, the street is 8 years old!!! Surely Audi update their nav data more frequently? Rant over! Nik.
