Greetings; just bought my first TDI, a new 2012 Jetti TDI with Nav and Sunroof. Driving back and forth to work mileage is great so far at ~36 MPH; much better than the 17/18 I was getting with my last vehicle. And plenty of pep when needed. My only disappointment to date is the rear view mirror; basic at best. Maybe someone out there knows of a replacement mirror that has a compass and does NOT require wiring and hours of painstaking installation woes.
