Hi,

It seems my Sat Nav sees no satellites (which i can see in the diagnostics menu). Consequentially my car is off the map.

Does anyone know how to easily test the GPS antenna? Is is located in the rear view mirror?

I have tried taking out an re-insterting the dvd already.

Cheers,
Dave.

COMAND NTG1 DVD Based.
 
Well if it gets no satellites it points to a faulty gps. First try unplugging the Comand unit fully or removing the fuse in the fusebox to reset the system fully and see if you still get no satellites. The factory antenna is built in to the back of the rear view mirror.

Easy way to test is buy a cheap gps unit off ebay and test the Comand system with that. e.g. GPS ANTENNA FAKRA MERCEDES COMAND NTG 2 2.5 4 DVD | eBay UK

Comand Online sell genuine and non genuine gps antennas used when retrofitting Comand:

Comand Online Ltd :: Mercedes SatNav/COMAND :: COMAND Retrofit parts :: Genuine MB GPS Antenna for DVD and Hard Disk COMAND APS
Comand Online Ltd :: Mercedes SatNav/COMAND :: COMAND Retrofit parts :: Comand GPS Antenna

You can use one of the above and leave it under the dash as done when Comand is retrofitted, the usual place to put it is on top of the cluster, it can 'see through' the dash.
