Navigation inoperative	Navigation CD-ROM not inserted or incorrectly inserted or incorrect CD-ROM Fuse in navigation processor (A2/30) Voltage supply for A2/30 CAN APS data bus	 CD-ROM is not upwards compatible Read out fault memory with HHT	Insert navigation CD, refer to: GF82.61-P-0001-03C AD82.61-P-2000-02B AD82.61-P-6000-02B AD82.61-P-4000B AD82.61-P-6000-05B
Navigation is faulty	Navigation CD not inserted or incorrectly inserted or incorrect CD-ROM Check variant coding and wheel calibration Navigation processor (A2/30) global positioning system (GPS) Reverse gear signal Vehicle speed signal	 CD-ROM is not upward compatible Read out fault memory with HHT Read out actual value with HHT	Insert navigation CD, refer to: GF82.61-P-0001-03C AD82.61-P-4000B AD82.61-P-6000-06B AD82.61-P-6000-16A
Dynamic navigation with TMC inoperative, radio UKW reception is, however, possible Code 815 only	Traffic data recorder (A2/43) Radio and navigation operating unit (APS) (A2/29) or CAN connection between A2/29 and A2/43 Navigation processor (A2/30) or CAN connection between A2/30 and A2/43	Test variant coding with Hand-Held Tester (TELEMATIK: YES) Test dynamic navigation with TCS (refer to Owner’s Manual).	AD82.61-P-6000-11A
Dynamic navigation with TCS inoperative Code 815 only, not code 348 (TELE AID)	SIM card is not configured for dynamic navigation CTEL interface (A34/4) Traffic data recorder (A2/43) or CAN connection between A34/4 and A2/43 Navigation processor (A2/30) or CAN connection between A2/30 and A2/43 Radio and navigation operating unit (APS) (A2/29)	Test variant coding with Hand-Held Tester (TELEMATIK: YES) Test dynamic navigation with TMC (refer to owner’s manual).	Configure SIM card, refer to GF82.61-P-0001-03C AD82.61-P-6000-13A AD82.61-P-6000-11A AD82.61-P-6000-12A
Messages from navigation are given too early or too late (e.g."Please turn to the right")	Check wheel calibration		GF82.61-P-0001-03C
Voice output is fragmented or inoperative	Language in RAM of navigation processor (A2/30) is partly deleted as a result of interruption in voltage Cables, radio and navigation operating unit (APS) (A2/29), navigation processor (A2/30)	Test HHT menu item"Voice output actuation"  Avoid violent shaking of A2/30 during language loading	To re-load language, refer to: GF82.61-P-0001-03C AD82.61-P-6000-03B
Radio or loudspeaker function disruptions, loud noise with voice output			Refer to DHB information / communication register 3 and DHB information / communication register 5
Display is difficult to read	Display contrast too weak		Adjust display contrast: GF82.61-P-0001-03C
