Hello & Welcome to Just Answer,
Sorry to hear of any issue with your device.
In order to help with this issue, may I ask:
1) Have you checked the "Navigation Settings' on the device, to see how they are set (such as "Faster Time, Less Fuel, etc.)?
2) Have you also checked the "Avoidances" screen, to see if any "highways" or "Toll Roads" have been selected in that screen?
3) Has your "vehicle profile" been set up and applied?
OK - can you tell me what the settings ARE - for each of those screens?
In particular, what is "checked" in the "Avoidance" screen?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
