: GPS is completely lost



06-12-2003, 09:28 AM
I've got a new 9-3SS Aero with the Infotainment + GPS Nav system. It only worked for the first week, and suddenly the car appeared to be somewhere it wasn't (Cardiff ... I was in Manchester). I visited the dealer, they disconnected the battery for half an hour, then sent me away again agreeing that it wasn't working. A week later they received a replacement part (Sat Nav ECU apparently) and fitted it - the GPS worked for about 20 minutes (the length of my journey) and when I got back in it ... I was parked in the sea somewhere near Swansea, according to the screen.

Now, either the car has an emotional attachment to South Wales, or something is amiss. I'm a little annoyed as I've wasted a couple of mornings and a lot of money. Has anyone had this problem? Is there a way to re-set the unit? I notice that the little compass in the top left of the screen doesn't point to North, could that be related to the problem? The dealer so far hasn't called me back and it's driving me nuts.

(Although it is taking my mind of the bloody annoying vibrations/rattling coming from the passenger door)

Hello,

About the arrow in the top left part
of the screen not pointing to the north could it be that you have not chosen that vision mode? remember
there are 3 different ways of representing the map...

About being in Cardiff instead of Manchester....letīs hope the GPS satellites are not down!!!

Also I took yesterday my 9-3 SS 1.8t Arc from the dealer after being in for small rattles in both front doors coming from the airbag -leather covered- area. They both went away -for the moment-. They claimed having put inside the wood rim a king of sponge that suffocates the vibration...

Good Luck with the GPS! (mine, apart from having some strange vibration of all symbols after some time is completely accurate..at least in Spain!)

Welcome to SaabScene, 356Pilot

Given your chosen name, can I ask what your other car is?

I have a '66 912, and there are a fair few other Porkers dotted around on here.

Just a thought, but could your GPS problem be related to the antenna?

Mine are getting some new parts in the beginning of July. As you might have read on another thread, my GPS is unstable. It sometimes hangs or refuses to start. I've also seen it getting totally lost a few times. In between, it works ok but I can't trust it which is quite annoying.

Cheers,
Stefan

I would say that it is the GPS ECU / brain which is faulty.

The only time when mine ended up in the middle of the River Thames was at a test -drive at original installation when the antenna could not pick up enough signal. It was relying on the gyroscopic sensor to position the car in the absence of any signal and gradually meandered off the map.

It wouldn't throw you out the distance of Cardiff to Manchester until a few days driving with no signal.

To move you just like that when you start up again after a 20 minute journey suggests the unit is faulty and nothing to do with your disk or antenna signal. (disk OK as it got you there - no antenna signal would probably still start you from where you had stopped)

I assume the system works by mapping vehicle position on your map software according to the long / lat co-ordinates supplied through your antenna to the unit....seems to me the only weak link would be the unit interpreting the data and needs replacement....unusual it should happen twice...

I can only relate this to my non-Saab aftermarket install and unifamiliar with the Saab set-up so could be all wrong !!

After a little bit more thought, it does seem strange that lightning should strike twice with the second unit malfunctioning.

It might be worth asking them to check every aspect of the installation. My installation manuals were very specific about mounting the unit (+/- 10 degrees), not having the antenna less than a certain distance from the monitor. Could be something that was not adhered to at installation - after all Saab are car specialists and not satnav specialists... Good luck !
