465T Routing/via point/stop error..

Don't feel bad about your frustration. I've had some similar issues with routing using the 2011.1 maps.

First off, check Mapsource. Be certain it is routing the way you need, fastest time and not shortest route. I had the exact same problem (or at least very similar) laying out a route with waypoints. Changing Mapsource to fastest time fixed a lot of those errors.

My experience is the routing with 2011.1 is it needs to be thrown out and a new baby brought in. For years we have had problems with the routing engine and Garmin's map encoding equating ramps and access roads the same as mainline expressway lanes. Garmin will also route you off the expressway to local roads when the local roads may be shorter in distance, but definitely longer time because of lower speed limits and stop lights. An example can be seen by creating a route from the Pilot in Cambridge Ohio (N39.99650 W81.57761) to Greensburg, IN (N39.33766 W85.48496). Rather than keep you on the 270 bypass around Columbus, it routes you through the city.

Actually a slight improvement with Mapsource on 2011.1 with road and address updates and finally figured out that 294 in Chicago is usually faster as default. However I called out Garmin on Atlanta issue and also Cleveland. Again my main issue is the routing points themselves--as you approach them, it will always re-calculate you back to them and same for your destination as you must stop for at least 10-15 minutes for it to finally say "next point"? or "you have arrived. The Pilot is right here! Why is it saying recalculate when we exactly hit the point? Sometimes it the option to go to the next stop will be grayed out therefore needing to reload your entire route when driving (when it does the recalculate thing when you use an intersection as a via point "add as a stop" When you "blow" by that point, exactly, it will say "recalculating" and your route will be destroyed. (calling it up again all the way from the beginning, which is a bummer) So we always need to hit "next stop" manually..however, you hit a bump and hit the 3rd via instead of the 2nd...you will not be able to go back until you reload the entire thing. I called Garmin as this is a safety issue because we should not have to fumble with the route manually when we import our own custom points or add them as a stop on the unit it self. It would be nice if just one thing "pops" up saying "you have arrived, what would u like to do?" "Mark as done?" "Recalculate back" or "Go to next stop" (Again this works if you do stop near your point for a min of 10-15 minutes. But you must stop. Rolling exactly through the point will not cut it. What I am asking is a little more hands free automation. Sorry for structural grammar, I have to write fast as we have to roll soon. Thx Jake

Fixing the routing won't be a trivial matter in any event. There are so many different pieces that come into play. The saying, Garbage In, Garbage Out is as true today as when it was first used 50 years ago.

If the map data is bad or incorrect, then the routing will be bad. If the map data has too many points describing road segments, then the calculation time is too long and the data that has to be stored increases and it takes more processor power to search. There really are a lot of factors that weigh in that are not apparent when we say "Fix the freakin' routing!"

I'm thinking an external antenna may help give you more accuracy. For $30 or so, it may be worth a try, and adds a lot of signal to the unit. I love mine!
