Thanksgiving adventures with Garmin
We have a unit that we bought about six months ago, when we needed to make a trip to Tampa for medical reasons. We were supposed to meet relatives for Thanksgiving at a hotel in the Buckhead area of Atlanta the other day. I wasn't sure I remembered the area, so we got the Garmin out and programmed it with the hotel address, and started on our way.
We ran into this: The previous times we've used the Garmin, it's been mostly travel on the Interstates. Well, from Huntsville, AL, to Atlanta there is no good interstate route -- you have to know and take secondary roads if you want to get there in a reasonable amount of time, and everyone that lives in this area has a route they prefer. Anyway, the Garmin had great difficulty with finding an off-Interstate route. At the start of the trip, it kept wanting us to go back the way we came and go to I-65, which would have us taking a much longer route. We got it to agree with us on the route we were using by setting a waypoint in Gadsden, AL (a town along the route). It then worked OK until we got to Gadsden, at which point it once again tried to put us on a route (U.S. 278) that I know from previous experience is non-optimal.
So once again, instead of it figuring the route for us, I had to tell it what route to use. I set another waypoint in Anniston, AL, and it then agreed with the U.S. 431 route we were taking. It did OK until we got to the waypoint in Anniston, at which point itinexplicably tried to route us around the back of a shopping center. So we turned it off until we got onto Interstate 20 and headed east to Atlanta.
At this point we didn't have much faith in its routing choices, so when it told us to gett off of I-20 at the Fulton County Airport instead of continuing on to I-285, I was a bit skeptical. Nonetheless, I went with it. Lo and behold, it found us an off-Interstate route that was an easy and quick drive! And the sightseeing was better to boot. We were at the hotel about 20 minutes earlier than I figured, and didn't have to sit in any traffic jams. Our relatives told us that it took the about half an hour to get through the trffic jams on I-285 and I-75. So go figure. In Atlanta, it did a good job of finding a route. In small-town northeast Alabama, not so much.
