My 2460 Was So Confused

I am guessing you had poor satellite reception, maybe because of the canyons or dense canopy? I have driven on the pigtail curves in the South Dakota Black Hills with my nuvi 855 and don't recall that it went bonkers like you described.

This happened to me throughout Eastern Oregon, Idaho, and parts of Montana while driving in the mountains. Sounds like your view of the sky has been blocked often with mountains/trees. Kind of annoying when it happens for long periods of time. I turned the volume off so I wouldn't hear Karen nag me about recalculating...

I had this happen a few years ago with one of my older Street Pilots while going through the Scranton, PA area. We came I-84 to 380 to I-81 then to I-80 and when we were coming off 380 onto I-81 the GPS went crazy. The GPS kept wanting me to exit and head into downtown Scranton, it showed the vehicle way off the interstate, and all kinds of crazy things. After we got a few miles past Scranton everything went back to normal. I don't think it had anything to do with satellite reception I think it was errors in the maps because when I got home I posted what happened on a GPS forum and two other guys replied they had the same problem in the same area. I've found the maps to be wrong in quite a few areas we have traveled through. One place south of Rockford, IL on I-39 at one time showed a rest area and exit ramp and there wasn't even an exit there.

It also happens when you go to a point and then backtrack out of the point to continue your route on the same road. It will often tell you you need to make a U-turn so you can get back to the intermediate point before continuing with the route.

Unfortunately, that occasionally happens when you are deep in the mountains, up again an occasional canyon wall.

Of course, it also happens in downtown Chicago ... where you are deep in a manmade canyon.

Satellites and GPS's have to triangulate to get a good fix on where you are and where you are going.

my 1490 can't get me home along the known best route in broad daylight with clear skies...

Hopefully this doesn't show up twice, I'm having net connection problems this morning.

Good to know I'm not alone with confused GPS readings in the kind of driving I have been doing. I suspect it is lose of a satellite and not the maps being wrong in my case, the roads that I had problems with I suspect have been there since they were game trails.

Jim...

It also happened to me while I was in Labrador, I thought my GPS was failing. Long way away from home to be without GPS! Of course, there aren't many roads up there to choose from, so I guess it wouldn't really matter:)

Ditto

Last night I was watching the show “Wild Alaska” and one of their planes lost the GPS function and the radio contact with Anchorage due to sun flare activity.

Hmm, I wonder how many of us Googled RAIM right after the show.

Then I wondered: WWAD?*

*What Would Ariel Do?

Sorry to get off topic, couldn't resist.

I too saw Wild Alaska last night. That was quite scary when he lost the signal. Those are some really harsh flying conditions there and I'd be very reluctant to take any flight there due to the weather conditions potentially deteriorating quickly.

As for Ariel, I'd have to pack some Depend diapers to get in a plane with her. From past episodes she most definitely needs to work on her landing skills.

My nuvi 2460 did not alert me to take the ramp on the right in order to continue on the same highway. This happened on Route 222 in Reading PA heading north to I-78 East.

Luckily I was able to accelerate to get around the other traffic.

Yeah, but she is SOOOOOO cute! It may be worth it.

After seeing where I was on the GPS screen I started checking the back seat for life preservers!

I was riding down a highway one day, perfectly in the the middle of the road with no problems. As I past by a mountain that was cut away to make room for the highway the GPS lost it completely.

You'll have these things. Weak sat signals, buildings and hills don't mix.

... and ...

Ariel's flying scares me too! On the other hand, I doubt there is a place or condition in Alaska her dad Jim hasn't landed with his trusty old 180, now equiped with MORE POWER!.

Ariel got her pilot's license!!!

That was a bad break for her having to do the final test with an FAA inspector grading her. She did well in passing but I still wouldn't get in a plane with her until she gets more experience.

Looks like the show will be ending with Jim selling the business that just he and Ferno started.

When this happens I just put the gps on sim. and use it as a street map. But I am always in the passengers seat so my husband does not have to look at the gps. I just read the gps like a paper map and tell him where to go.

always tells me where to go too. She doesn't know how to use the nuvi tho.

I hear ya and feel your pain.
My wife doesn't even know how to plug the Nuvi in, yet she always knows better. I think there are two distinct species of humans.

We own some land in NC, along a private twisty road, and have encountered that as well....
I'm going to guess it is the twisty road map that is at fault.... the map twists and turns don't match the road twists and turns.... and consequently the Garmin looses track of where it is, as the road is twisting differently than the map it thinks is correct...

Actually it is no difference than a parking lot in a city... Garmin doesn't know about the parking lot, and you turning up and down rows of parking rows confuse Garmin because it knows where the roads are, and you aren't there...

Same thing happens in parking lot in Chicagoland or private road in mountains of NC.

Similar thing happens with expressway service roads that closely parallel the expressway. The GPSr takes a while to realize I'm not on the one it thinks I am. I guess it's mostly a function of civilian GPS signal accuracy, but fun to watch (when I don't need the unit's help. Not so fun when I do!)

On some occasions, while traveling usually on a parkway, I get an audio alert of a red light camera ahead. The camera is located on the road which is on an overpass of the parkway.

I wouldn't do a thing like that

I know what you mean about parking lots. Got lost in one in Carmel, Ca and went around the mall (small one at that) several times until I could find where I was going.
