when I come up to a intersection, the pointer is not yet at the intersection.. after ive driven through the intersection, the pointer reaches it shortly afterwards.. Same thing with bridges going over rivers, I can be just past the river but the pointer is showing I am just about reaching it... has anyone taken their car in for this and if so, what did they tell you/ or what did they have to do to fix it? Thanks..

 

Depending on how far off you are, it's perfectly normal, Mine runs between 1 and 3 meters off depending on relative speed etc. I just compensate by going to a more detailed view if I need to.

Do a search in this forum for a thread that describes how to get into the Navi troubleshooting screen, in there there's a choice to show how many satellites you're tracking. Any more than 3 and you're fine.

 

Mine has a slight lag in it also, but I would consider this normal since GPS in accurate to a range of 2-4 meters, which is dependant on antenna location, satellites, etc. Thankfully the DOD removed Selective Availability from the GPS satellites in 2000, otherwise you'd be off by about 100 meters....

 

There is a simple explanation for this. The navi antenna in located under your rear package shelf so the pointer on your screen shows the location of the rear window. When your rear window is in the intersection your arrow on the screen will be right on the map. Try it. It is true!
