GPS Display - Strange Things Are Happening.

[ctrcbob]

As Red Buttons used to say, "Strange Things Are Happening"!

A few weeks ago, I filled up at a gas station about five miles from home. When I started for home, I noticed that my GPS display showed that I was about a quarter mile from where I really was. Stayed like that until I was almost home, then "blurp" it corrected itself, and showed my true position.

OK, I figured it was some kind of a fluke. All was well until today. On my way home, I again noticed that my GPS display showed that I was about a quarter mile from where I really was. Got home, and display still was wrong. Half hour later, I moved the car, and display still wrong. Another hour later, on the way to the grocery store, "blurp" it corrected itself. This time, I had checked other screens, and the Nav Info screen shows that I have no Sat. signal, even though I had the arrow and map moving but in wrong position. Also, the Navi MPH worked correct, but the position (latitude/longitude) was not working. OK, all is well again.

Then I got to thinking, this second time, it again happened when I left THE SAME GAS STATION as the first time. I have no idea if that has anything to do with the problem, however "fool me once, shame on you; fool me twice, shame on me" and there will not be a third time at that gas station.

(Any of you "Old Timers" remember Red Buttons singing "Strange Things Are Happining"?)

Me thinks you spent too much time in Roswell!!

I had they same issue on a couple occasions. The MAP seems to drift. The blue dot bread crumbs where not synched to the streets I normally traveled and my position displayed showed I was off roading. Then all was fine.

I assume it was due to GPS internal or external not linking correctly.

Was going to stop into that same gas station today to buy some chicken wings, but decided not to take a chance. Its just strange that the only two times it happened to me was when I left that gas station.

Won't be able to go out to Roswell until September or October. (Darn). Have not been out there since last December. Will also spend some time in Ruidoso.

Leaving for Penfield (Rochester) on Friday. Will also spend some time in Saratoga, Ballston Spa and Lake George. Will return to Florida sometime in June (when its HOT HOT HOT )

Could be an issue with the GPS chipset + their algorithm.
I know of a very similar issue on a different kind of module which also utilizes GPS.
Had a hard time troubleshooting the issue- spent weeks trying to root cause the problem.

Fortunately, this hasn't happened on mine yet and I wish it keeps to be that way.
Let us know if the issue worsens.

Good thing it wasn't your house. Your wife would start wondering where you disappeared to.

Could be a software issue. I'd check the antenna connector on the GPS receiver for a bad connection / loss of signal.

I agree with Dave. Garmin and probably others, have made GPS that tie into speedo and compass to enable dead reckonning when signal is lost due to high buildings, trees etc. Don't know if your nav has that capability but sounds like it, especially when you said system showed no sat signal. If that's the case ant, cable or receiver are possibilities.

Before my GPS went south, I had an errant-pointer event while driving near a copper mine in CA. Then another time, just on a street somewhere. As I reported in another thread, I eventually had the "No Reception", from which it recovered once but then returned several days later and stayed permanently. I'm not suggesting the errant-pointer is a precursor to total failure, just reporting my experience. Replacement unit will not be available until June 13, so I'm glad to be back traveling my familiar home roads.
