Goofy Garmin? Routes like a drunk.

Former Member over 10 years ago

We gave our Garmin verbal instructions to go to a nearby restaurant as a test.
We knew the easiest, fastest most direct route - but the Garmin took us off the main thoroughfare through a bunch of side streets to get there.
Another test with Basecamp is just as scary.
We know that there is a very direct route from Phoenix to Puerto Penasco, Mexico.
So, as a test, I programed the start and end points and got a route that takes us hundreds of miles off course.
Attached is a screen shot of the goofy Garmin route and a dashed line illustrating the correct route.
What is wrong?
Should I return this new 2699LMT to Costco for a refund?
Or is there a fix for this nonsense?

Oops, I misspoke in my first reply. I used the "Car/Motorcycle" profile in Mapsource with "Auto-routing" as the route style.

So if it works for Dave something must be different between his setup and yours. Basecamp version maybe, since 4.3.5 is an older one?

I don't currently have 4.3.5 loaded but could load it if you think that could be the problem. I do have 4.2.2 loaded on an old XT computer I never use any more. It gave me the same routes as my other system based on State Highway avoidance or not.

Probably not necessary, I guess you're on 4.4.6? Need to know what the OP is running.

I have no reason to believe it's 4.3.5 that's the problem. It happens to be the version that's currently on my computer. I hardly ever use Basecamp so I don't make any effort to keep it current, especially when you never know what they're going to break next.

Seems though like the only difference may be the Basecamp version :confused:

Using the "Trucking" profile in Basecamp (4.3.5) gets the right results. I made no changes to the profile defaults.

Okay, just to make you happy :) I updated to 4.4.6 and it does the same thing as 4.3.5. The Driving profile pushes the route way west onto MEX-2 at highway 95. The Trucking profile does it correctly down highway 85.

Hmmn ... so why does Dave's work correctly yet yours and the OPs doesn't :confused:

Yes 4.4.6.

I'm going to regret doing that, aren't I? Isn't 4.3.5 the last version where Garmin doesn't force the updates of the beta versions? Now I'm going to get stuck with every new update as soon as it's released whether I want it or not; whether I want to do the update at this particular moment or not???? Arrrggghhhh. Now I have to go track down a copy of 4.3.5 and reinstall it. :(
