Just bought a TOMTOM GO PROFESSIONAL 620 and in 3 days I did 7 routes and my sat nav didn't show me once the correct route, even google maps was more precise than this product. What can I do ??? Why is doing mistakes , that a free soft from internet that I was using is more accurate, even google maps was showing the correct route , and its not designed for trucks! I load some pictures with some examples, the red arrows is the correct route, some casses I have missing streets. hopefully someone from TOMTOM customer care will answer me, because I tried to contact them by email and was impossible.
