1490T Portable GPS Navigator Quirk: If you are using the traffic information and have the traffic avoidance enabled you can get some really odd routes, since I was just trying mine out around town and to work and back I knew it was telling me wrong turns, a little time in the manual and I found out why, it was automatically altering the route around traffic alerts, while this may sound like a good thing and would be if it told you it was doing that, in my case it was not, no other route is going to help and I did not know what in the heck it was doing :)

1490T Portable GPS Navigator I found you can have the best of both worlds, keep trafic information turned on but disable traffic in the avoidances setting tab. Then it warns you of traffic on your route, lets you see where, and gives you a detour option at that point you can take or ignore. It would be better during the route calc process if it said it had added detours, and when it does it on the fly it should also, minor quirk once you know.

This is a 3 star feature in the auto mode. 5 star would be to tell you and offer y/n detour options for each point.
