I'm on my way home from Mexico now. Just outside Indianapolis, Indiana I directed the 3790 to take me home by hitting the "Home" button. Simple right? I live in Toronto, Ontario, Canada. So the simplest route would be via Detroit and then home. At that point about 600 some miles.
What does the GPS do? It routes me south of Lake Erie, via Buffalo, NY and Rochester, NY then via the 1000 Island bridge and then west on Hwy 401. Total distance about 2,164 miles!!!!!!! WTF!!!!!
GPS is set for fastest route.
Theoretically I do not need the GPS from here on, but what the he77 why not use it. My old trusty 855 never acts up like that and that's why I carry it as a backup for the 3790!!!!!!!!
Is the GPS set to avoid tolls? Is there a toll road or bridge on your expected route? Other avoidances set?
Some related discussions?
Yes Craig it is set to avoid tolls. But that has never stopped me from using the Ambassador bridge. In fact the 1000 island bridge is also a toll bridge as is the Ambassador bridge and the Detroit/Windsor tunnel.
In Mexico I use every toll road along my route. Once North of Mexico I avoid any toll roads.
Strangely enough this has never happened before using the toll avoidance settings.
Actually once I used a preset route which included the Ambassador bridge including the toll avoidance setting the GPS once again complied.
Damn temperamental Garmin!
I've never understood your Nuvi NOT taking you on this exact route when we have discussed the "toll avoidance" in other threads. I have owed or used every model Nuvi since the original Nuvi 350, with the exception of the 8XX series and everyone of them as given me the exact route that your 3790 just gave you with toll avoidance set to on.
IMHO if your 855 doesn't do the same thing then it's the 855 that is acting "really stupid" and not the 3790.
Except for the last few years, I lived in southern Ontario all my life and traveled back and forth into the US several times a year. As far as I can recall there are no crossing points from Sault Ste. Marie to Cornwall that doesn't require a toll be paid. The one possible exception is the 1000 Island Bridge which, if I remember correctly, requires a single toll, coming from the US or Canada to one of the islands (one island is Canadian and one is US) but no toll to get from either island to the mainland of either country. I can only assume that for many years the Garmin map data incorrectly or not had this bridge coded as "toll free".
I just checked your route using the newest maps (2015.40) and you'll be happy to know that, at least on my 3597, Garmin no longer considers the 1000 Island Bridge as toll free, and now routes me from Indianapolis to Toronto via Montreal. A considerably longer trip than the one you got.
The one interesting thing is that a route from Toronto city center to Indianapolis city center will not take you to Montreal but to Fort Erie/Buffalo. Thats because the Peace Bridge is only tolled in one direction (US to Canada) and since this route is going from Canada to the US the avoidance is applicable.
On your other post, if you had a "preset route" entered with the Ambassador Bridge as a waypoint the Nuvi would have directed you that way whether you had the toll avoidance set or not. AFAIK the waypoint would have overwritten the avoidance setting.
Just an FYI, I'm not sure where you were in Indianapolis or where you were going in Toronto but from city center to city center with faster time set and avoid tolls off on my 3597, the route provided is via the Blue Water Bridge in Port Huron/Sarnia. That route involves no driving through any large cities like Detroit, or Windsor and is only 525 miles long. But you likely know that and prefer the Detroit route.
IMHO if your 855 doesn't do the same thing then it's the 855 that is acting "really stupid"
Since the 855 is a backup and rarely used, it may well be that the 855 does not have a toll avoidance set.
Did you cuss at it?
Did you call it names?
Did you refuse to let it play GPS games?
Perhaps you deserve it misbehaving
The next time BEFORE you go back to Mexico this fall/winter put the unit in simulation mode and see the way it routes you. If you would like it to take you in a different way, just add vias forcing the unit your way and voila the job is done !
From past experience the routing on my unit has changed with map updates (most probably the addition of new roads, exits etc) and I just add a via and contnue on my merry way.
On long trips BEFORE leaving you should always simulate the route to avoid exactly what your experiencing. The old Gurus around here also taught me as precaution to always do a hard reset of the unit when upgrading the maps and or software
sounds like its time for a new one
I'd give it to an in-law I didn't like very much!
Just got home after this 4,700km trip and I think my next step will be a complete reset after I save all favorites and POIfactory POI's. I'll also do a complete backup before doing anything else. This GPS was already replaced by Garmin shortly after I got it.
Another really strange thing happened along the way. Every once in a while the 3790 jumped out of a set route to completely different screens, i.e the command screen as if I wanted to voice command the GPS to do something. Or it went out of the route to a zoomed out screen and to get out of it I had to hit the return button(arrow) on the left bottom of the screen.
BTW the voice command wake up has been changed to "Wake up now dummy" to avoid any possible radio interference.
I'll reset the 3790 to factory to see if that will remedy these problems and download the newest map too.
Both, the 855 and the 3790 have the identical settings/avoidances set.
