82 858 52	The GPS antenna can cause problems with the reception.	If this complaint only occurs occasionally, it can be reproduced in some cases by moving the antenna housing.
	Affected are those GPS antennas with production dates between CW 41/02 and CW 06/03 (the date can be found imprinted on the end of the plug for the telephone behind the right trunk lining, see figures).	Important in this case is that the GPS antenna is not covered with a hand when being tested. This could cause a failure of the GPS.
	Wrong directions are given in the navigation mode or the navigation is incorrect. Despite good reception outside in the open, there is still sometimes no satellite reception.	1 Check the production date of the GPS antenna.
	Affects vehicles with COMAND as of Navigation DVD 2.3 in navigation processor.	If the production date is between CW 41/02 and CW 06/03: ↓ 2 Remove/install/replace GPS antenna.
