Map Question
Can anyone enlighten me regarding the red / yellow colors on these secondary roads.. I am aware of the traffic integration with XM but these aren't covered roads.. I have deselected traffic info and these colors remain... also they are not part of the Google overlay. It seems to have absolutely no correlation to traffic conditions but for the life of me, I have no clue why they are colored differently ( or even at all since most other secondary roads aren't)..

They are related to traffic, I have the same thing on mine. They're either part of Google Earth or hardcoded into the map data on the harddisk as I'm not using Sirius traffic.

It is the overlay coming from the MMI maps. It has nothing to do with traffic, but type of road.
Red - Limited access Freeway
Yellow - primary surface street
White - secondary streets
I believe the logic will prefer Freeways and primary surface streets when recommending a route and try to use secondary roads only to get to and from a higher level road unless the estimated time penalty would be too great.

Your logic seems good, just doesn't agree with my map, which reflects traffic density, although not real-time so it isn't worth much.
