S4 Sat Nav Problems

[boulevard]

I have just got an S4 cab with sat nav. Sometimes it doesnt find any satelites and then the sat nav then just locks on to any road the arrow happens to come across.

Any clues as too what might be causing this, where about is the gps located on a cab?

Thanks

1st remove the radio & check if the antenna has come unclipped mate with the assumption its an audi unit.

Thanks for reply. Its the standard Audi MMI unit in the car. Sometimes it works, and others it wont find a thing. Its bloomin annoying,
