	Troubleshooting
Complaint	Cause	Note	Remedy
Radio and navigation unit (A2/56)  completely inoperative	Fuse in A2/56, Voltage supply for A2/56, Defect at navigation CD-ROM, A2/56		AD82.61-P-6001-01A
No communication  possible between Hand-Held Tester (HHT) and Audio 30 APS	K line, Radio and navigation unit (A2/56)		AD82.61-P-6001-02A
Navigation inoperative	Navigation CD-ROM is not loaded or is incorrectly loaded or incorrect / defective CD-ROM Radio and navigation unit (A2/56)		Load navigation CD, refer to: GF82.61-P-0002-03A
Destination finding system messages  are given too early or too late (e.g. "please turn right")	Check wheel calibration and variant coding		AD82.61-P-2001-03A
The expected arrival time  is not correct	Time on radio and navigation unit (A2/56) is incorrectly set		Actuate "NAV" pushbutton and activate "CLOCK" menu, set time
Navigation is defective  or imprecise	Check variant coding and wheel calibration, Reversing signal, Wheel speed signal, Models 163, 168, 208.3, 210: Cellular telephone and GPS roof antenna (A2/49), Models 170, 208.4: GPS rear antenna (A2/23a2) Radio and navigation unit (A2/56)	Models 163, 168, 170 Models 208, 210	Refer to: AD82.61-P-2001-03A  AD82.61-P-6001-04A  AD82.61-P-6001-04B AD82.61-P-6001-03A  AD82.61-P-6001-05A
No reception of GPS data	Antenna cable or Model 163: Cellular telephone and GPS roof antenna (A2/49) or cellular telephone and GPS antenna splitter (A2/57) Models 168, 208.3, 210: Cellular telephone and GPS roof antenna (A2/49) Models 170, 208.4: GPS rear antenna (A2/23a2) Radio and navigation unit (A2/56)	On model 163 only one antenna cable (for telephone and GPS) leads to A2/49. A defective antenna cable would therefore effect a telephone, if connected.	Model 163 AD82.61-P-6001-05B  Models 168, 170,208,210 AD82.61-P-6001-05A
Radio or loudspeaker functional faults and poor sound with voice output	Loudspeaker system or amplifier outputs of radio and navigation unit (A2/56). Only with sound system (code 810): Left/right audio power amplifier (N40/3)	Antenna amplifier test can be carried out using HHT.	Refer to DMNL information / communication Index 3 (RD) Index 5 (LS)
Voice output  is fragmentary or inoperative, but audio signal replay (e.g. CD player) functions without complaint.	Voice in RAM of navigation computer  is partly erased as a result of an interruption in voltage supply. Data fault on navigation CD-ROM Radio and navigation unit (A2/56)	Avoid excessive shaking while loading voice on A2/56.	Replace CD-ROM
Illumination  of radio and navigation unit (A2/56) inoperative (with terminal 58d, ON)	Terminal 58d signal is not on radio and navigation unit (A2/56)  . On models 208, 210, terminal 58d is not connected, because A2/56 is connected to A1 via CAN.		AD82.61-P-6001-06A
