SL Sat Nav receiving zero satellites
I took my SL into the main dealer to have the Sat Nav fixed, it was showing Zero satellites received and the clock was also wrong.
They looked at it and returned the car to me with it in the same condition, saying that because I had a copy CD in the head unit, that was most probably the problem, even though it wasn't showing a "read error".
It was suggested that the Command head unit was faulty and should be replaced. This is very expensive, but I found one.
Just before paying a fortune for it, I decided to try the old computer trick. Switch it off and back on again - in this case I disconnected BOTH batteries for a few minutes.
Connected them back up, the clock reset itself and the Sat Nav can see 6 satellites again!
How come trained technicians can't do this? I nearly spent £1000 on a complete waste of time.
I hope this might help anyone with loss of Sat Nav in an SL or any other model.
