I recently had my windshield replaced. Since then the navigation system is "lost" in that it has my location about 75 miles west of the actual location. This puts me somewhere deep in Stockton, CA.
It tracks movement, but again offset.
I've called the company that did the replacement and they came out, checked that the glass was correct (had the antenna) and was connected.
What next? Would disconnecting/reconnecting the battery work? Or is this a PIWIS issue that I have to take to the dealer?
Your help getting back home appreciated.
Thanks,
Bob

Sounds like the same problem. Probably a bit of road that is not on the map and it gets "lost".
If its the same problem, turn off the PCM, turn off the car. Go to a road you know is on the DVD, like an Interstate. Turn on GPS and set to a new destination. It seems to work when you do that but if you hit a piece of road again not on the DVD, it seems to get messed up again.
No just lost...
Thanks, but I did try that, for example setting destination to go home. Still lost.
Its not a matter of being offroad (I have the extended navi). I'm talking about being in my driveway, at home where there is a mapped road, clear reception etc. So its more fundamental than that.
Thanks
The GPS antenna is under the plastic cowl that is removed while replacing the windshield. Do you suppose it's possible this was unplugged?
See article below:

The installer said that they checked that and it was ok. I just tried to check it by removing the battery cover, and feeling under the cover, but did not know where exactly to hunt for. I could not feel anything that seemed like the connection. Where is the connection located? left, right, middle?
Should be on the driver's side cowl just underneath the windshield. Also, the antenna that is in the windshield is for the radio and not the GPS. Instructions for this are in Ken's article. There is another way to see if the unit is picking up any GPS satellites. I'm away from my car right now, but I think it's under the "info" button on the PCM. It will you how many satellites it's receiving a signal from, altitude, etc. If it shows 5, 6 or more, then the antenna is most likely hooked up.
Also, you could try to reset the system to see if that corrects the problem. Simply pull the fuse. If you try both of these, and it's still 75 miles off, then it's a whole different problem from what I'm thinking about.
That is a VERY BAD sign.
Stockton is not where you want to be.
You live in the hills, or did you mean "East"?
I have 7 GPSs.
(Don't ask.
) I have had them be a block or two off track. (In other words the pointer was moving on a street parallel to the one that I was actually on.) When traveling in Europe I have had the pointer several meters off the road. I have never had a GPS seventy miles off target. I suspect that the GPS antenna is not hooked up or hooked up wrong.
I know that your GPS is a factory install and therefore in-dash but for all of us who use hand-held GPSs an add on antenna is helpful. There is something about the glass in a Cayman windshield that some times blocks the signal. I bought an add on antenna - that plugs into the GPS and sits on the dash beside the GPS - and solved the problem of bad reception.
Oooops: I meant East. Perhaps its me who is lost?
I'll pull the fuse and see what happens. Perhaps I'll warp to the 'Ring? If only....
