A second issue has to do with strange routing that nuvis using the NTU version seems to give sometimes. For example:

Black color is the right route to give but for some reason device suggests the red one.
Another example:

Instead of keeping the route on the main road (yellow color) device suggests the red colored one.
Avoidances
U-Turns
Traffic
Carpool Lanes
Unpaved Roads
Calculation Mode
Faster Time
If we use the same NTU map in MapSource or BaseCamp routing is very good with no problems. The problem seems to improve if the user rename SID & SQLite folders, clears Travel History and deactivate it together with trafficTrends.
I must inform you that we have Auto Drive Hellas, a map from the local Garmin's representative here in Greece that works great with no problems at both cases i described earlier. This map has been our tool to compare routing & functionality problems with City Navigator Europe NTU.
Thank you in advance for your time and patience, i hope you'll come to a solution soon.
P.S
Sorry for the off topic, if there is a suitable section for it please move it there.
