I think the quality of the RTTI data must be dependent on the city on which you live, not iDrive. I have a car with the 08 system and the 09 system in the M3 and there are two differences that I have noticed....the 08 system retrieves the data faster (possibly because it has the option to select the FM signal with the highest strength). The 09 system is much more accurate...to the point where it is confusing. An example of this is the way the 09 system creates separate traffic alerts for events that may be less than 1/2 mile away and be accurate. Traffic actually lightens for a short section and then gets heavy again (happens all the time in Houston). This creates too many events IMO and creates confusion.

Living in the 2nd most congested metro area in the US, my nav screen is more cluttered with alert icons than there are roads. I can barely see anything else on the map.

I've finally stopped using it, because I was becoming dangerous trying to cancel the traffic bulletins offering me endless new detour routes. After 5 or six offerings, I usually ended up getting a message that no detour is possible, and after trying these detours, they usually added more time than the delay estimate on the original preferred route. I think a global message, "Traffic Gridlocked Everywhere--Flip a Coin" should be added to the 1st priority warning list.

Talk about a prescription for a distracted driver. I might as well have been texting. I don't remember seeing a thread on this, so I thought I'd start one.
I use the dynamic setting, where I just let it automatically choose a new route as traffic conditions change. Most of the time it's correct. I am guessing that if your area is the #2 most congested that my area is #1, so I understand where you're coming from about the endless flood of updates and suggested alternates.

That's what I was using, and my experience has been entirely unsatisfactory. I have left it on, for the time being, but now I hit ignore, for the most part, because it has cost me entirely too much wasted time. I only leave it on as a monitor.

It is a rare day, where it doesn't try to detour me at least 3 times on each leg of my daily commute. I've tried the detours, and I've tried following the normal route, and 90+% of the time, sticking with the predicted, delayed, main-route has been a shorter route than the suggested detour.

This was just a bit of an experiment for me, and I kept track of the results for about a month, with about half of the sample following detours and the other half simply ignoring them--same route destination on each end (home and work), every day.

I've now concluded, ignoring is best. The info database feeding it is just not up-to-date enough, and the reported problems are often resolved before reaching that point. The database here doesn't include side-street conditions and number of stop-lights, which are often part of the recommended detours.

Since you live in the "land of freeways," perhaps your alternatives are better and/or your traffic database is more "real-time."

I hate to say it but RTFM...

In my manual the discussion of this feature with exact instructions begins on p153. It is likely different for the Canadian manual. Get a pdf version of your manual and then a search for "traffic" or any other key word happens as fast you you can type.
