320d nav problem
 

Hey guys,
All of the sudden lost GPS signal. It shows that I am about 10-15 miles away from my house, even though I am parked right next to it. The little window at the top right has no green dots (sattelites). I also tried to disconnect it from the power and reconnect it back in 15 minutes, but the issue is still there. I went into the service menu and here it is:

almanac: No
Visible: 8

wheel sensor: 0
satelites: 00
GPS status: Receiver Error
Gyro: 2500-2503 (Either or)


Any ideas?

Thanks!

Your GPS has a receiver error

Likely the GPS antenna has died. Try another antenna.

Is this correct??? if you look at the screen, there is no green dots etc, so it looks as if it isn't even searching for a gps signal..

And, does anyone know how to remove the sharkfin aerial for my e46?

Thanks in advance

No green dots = no reception = bad antenna

Sharkfin aerial is for telephone only. Removing will damage paint and leave a hole in the roof. I would not remove the sharkfin !!

GPS antenna is under the rear parcel tray, below the rear window.

Any ideas how to get to it (do you have to remove the parcel shelf (my cars an e46)

Thanks

Ash - as mentioned by Kiwi you need to take both c-pillar covers which is located in your rear window.

These covers have Torx screw behind the light fixture. Remove the light fixture (clips) and unscrew this screw before pulling out the trim (2 clips are attached to the pillar, #8 in the drawing).

I got the drawings off from a fellow fanatics.

Here's a link to a retrofit pdf, it has all the wiring diagram for nav system:

Thanks Guy's...

I have pulled the back pannel off tonight (in the boot, where the carpet covers all round the nav unit), and I saw where the nav aerial plugs into the loom, but what confused me is that there is a plug that runs along side the aerial cable (it's a small flat plug with 3 wires)

I was wondering if that has come unplugged from somewhere?? I had a quick look but couldn't find anything.. does anyone know what this is???

The 3 wires could be your optional Aux connection, should have a plug. Doesn't go anywhere, unless of course you have an aux input.

When the Almanac is gone that means you lost power somewhere and lost the memory. Since, you don't have sat coverage, your car will not be able to get the Almanac (Date and time). It will have to do a search and this could take a little while...I do not know the time frame for this system.

Just make sure everything is tight, fire her up, and see if the system reboots. I would wait at least 15 minutes to see if it acquire sat coverage.

Tell me your chassis number and the 3 x wire colours, and I can tell you what the plug is for.
