    Anybody having navigation issues?

    A few times a week my nav system shows my car being in various bodies of water in the nearby area. It's sort of entertaining - watching the system trying to find close roads on which I might actually be driving but, then puts me back in the water. Kind of defeats the idea of a guidance system. Anyone else having this kind of issues?

    Re: Anybody having navigation issues?

    When I pass through the Blackwall Tunnel in London (which runs under the River Thames) and have reached the northern side, while I am still in the tunnel underground, the satnav suggests making turns etc into streets that exist on surface level.

    The satnav disc is May 2006 and this tunnel has been around for about 40 years. Strange!

    Re: Anybody having navigation issues?

    I have noticed that the sat nav on my 997TT had given me the same thing a couple of times in the past few months. Usually it was not far from the actual location, but it took at least 5 minutes for it to get back its bearings. Strange. No such problem on my Cayenne.

    Re: Anybody having navigation issues?

    gotta like the in the water deal....i like it when you can get in the nav systems head about a particular route....still like paper maps, quite a bit

    Re: Anybody having navigation issues?

    Every time I switch from the map to the trip view, I get a message at the bottom of the screen saying "incompatible nav software." Anyone know what's that about? Mine works fine though.

    Re: Anybody having navigation issues?

    Someone wrote elsewhere that this could be an antenna unit going bad. Report it to Porsche. I have had none of that in my Extended Nav in my 997S Cabrio.

    Re: Anybody having navigation issues?

    No, I haven't had that error message on my extended nav system.

    On Saturday, I enjoyed one of the nav's really useful features. There I was with my wife, tired and cold, after a day's shopping in Central London, in need of something warm to drink. We wanted to find a smart hotel in London where we could go for proper hot chocolate. We just selected POI>nearby which helped us find nearby hotels. Superb!

    Re: Anybody having navigation issues?

    easy--so true! Months ago I arrived late in Kaiserslautern without accomodations. I drove and drove around that town looking for a decent hotel. And then I thought,--I have a nav system with all that POI stuff in it! What was I doing?? I selected hotels, it listed them by distance from my current position,--and I choice one quickly about 4 kms away (out of the city center). I arrived at a beautiful place on a lake/pond and spotted a 996 Cab in the lot,--it had found a place!

    Your turbo wants to go for a swim.
    You should have your dealership reinstall/reboot the nav. system.

    Re: Anybody having navigation issues?

    True story - summer 2005, rented an E-class in Switzerland to drive from Zurich to Lucerne. We wound up on the wrong side of the lake from the hotel, and the stupid GPS kept telling me to make a left turn in 200 meters ... which would have gotten us very wet. Finally switched it off and asked someone, which worked fine.

    The P GPS put me two blocks off of my real current position once since I've had it; problem corrected after a few minutes and hasn't reoccured. This was on my daily commute route.

    Re: Anybody having navigation issues?

    My navigation is a few blocks off today, failed to reset it (already tried removing both PCM fuse and DVD).

    Read through the menu but there is no info about recalibration. Also drove the car for half an hour but it hasn't fixed itself.

    Any suggestions? Bad antenna?! Please tell me I don't have to visit dealer.

    Re: Anybody having navigation issues?

    Keep in mind that if you are in an urban center or other locations with a limited view of the sky that the GPS signals can be blocked from one or more satellites. When too few satellites are in view, the quality of the positioning can drop off significantly.

    If you are in a wide open area and you are having these problems it is a different matter....

    Something's wrong. After pulling the fuse and the CD The thing should re-initialize and correct itself. Especially after 30 minutes under open sky. Mine did.

    I think I know why my navigation's off

    It happened after the new windshield was replaced. I bet the installer didn't properly connect the antennas from the glass to the A-pillars.

    Let's hope there is an easy fix?

    numbers 28 and 21 are the antennas.
    21 is the nav system antenna

    I also thought they were in the windshield, but apparently not.

    did they get disconnected when windscreen was installed?

    I thought the antennas were disconnected based on:

    http://www.rennteam.com/showflat.php?Cat=0&Number=124828&page=&fpart=all&vc=1

    It's interesting however, they stopped working after the new windshield has been replaced?
