Navigation system shows incorrect current location after body shop visit.

I hope this is the right place to post this.

I have a 2006 E350 that was recently broken in to by someone who smashed out the sunroof.
Among other things the roof got scratched and the body shop had to paint the roof. The body shop told me they removed the windshield and rear window to paint the roof then replaced them.

About a week after I got the car back the Nav system showed my current location as being about a mile from my house out in the Gulf of Mexico. I just thought it was confused as it later showed the correct location. Today it did it again and shows my location as 1/2 mile or so away. The bottom of the nav screen does not show the coordinates or satellites like it did.

I am assuming the black antenna at the top of my rear window is the antenna for the nav system.

I am wondering is it possible the body shop did not hook up the antenna properly or did something that would cause the system to not get a fix from the satellites?

thanks for any assistance

Is this the pre-facelift W211 Sedan model if it has the GPS antenna at the top of the rear window (the facelift has it on the roof)? These are prone to fail but you could check the connector at the far front/left/top, near the hinge at the trunk.

You should also set the COMAND to show how many satellites it can detect. If it shows "-" the connector is unplugged or the cable/antenna is broken. If it shows "0" when it should not, it must be the antenna.
