Dear All,Having enjoyed nearly 10k trouble free miles in my Q3, sad to report, totaly failure of the full Sat Nav - car thinks I'm in Antwerp - calibration related issue, GPS sensor/antenna issue - don't know.Sadly, nor do the two Audi dealers I have taken the car to...2 days wasted and no Sat Nav for the last 3 months...escalating to Audi Customer Service - will keep you posted on how I get on...not impressed with dealers ability to troubleshoot the problem and worried the factory build quality integrity will be lost when the dealer starts ripping the car to bits...lets wait and see.RgdsPrashan
