I get there without a problem, but for some reason the unit wants to change to a longer route coming back. Why would it change routes between the same two points?
My TT does that and I figured out it's because of one way streets, access ramps, and such that it will do this. Going to a location you can take a certain path but that path may not be reversible. Or the GPS might be stupid.
There is also a supposition that Garmin routing tends to prefer right turns versus left turns. The theory is that it is safer to make a right turn rather than cross traffic to make a left turn. This would affect routing back along the exact same route.
I assume when my 680 does that it's taking a traffic red flag or two into consideration... next time it does that go over to your traffic window and look at local incidents/slow traffic and see if anything is in your preferred route that it is working you around.
The first time that happened to me I reproduced the trip in Streets and Trips and it did the same thing.
Well it's not left turns (aren't any), and I don't have traffic. It could be the ramp configuration, but in this case the route could not be more straight forward. It's just two turns, no other logical way to go, and the unit makes the same mistake every time.
perhaps it is a function of your avoidance's, or that there is enough difference in distance on the way back that it's a shorter drive via a different route.
It's not the avoidances... no ferries in these parts. Guess I can live with it, but the wife, who's not into teckno, is laughing at me and my Nuvi.
take two cars to the destination. you drive back following the GPS. she can drive back EXACTLY the way she came. may the best man win
Did you try and do a detour and see if that takes the route you want it to.
I guess garmin's a republican as opposed to being on the left as in democrat...
