Notes on installation of GPS antenna
The GPS antenna should be installed only in a vertical position with a maximum deviation of 10° from
horizontal.
The GPS antenna should always have a free view of the sky. Thermal insulated windows can significantly
reduce the function of the GPS antenna.
When installing the GPS antenna, always ensure that the arched surface points away from the vehicle.
Changing the installation location inside of the vehicle after the system is put into operation has no effect on the
GPS reception.
NOTES ON RADIO CONNECTOR PIN ASSIGNMENT - AH82.61-P-0001-05A
Model 163
The pin assignment in the radio connector has been changed on vehicles as of 07.99 (model year 2000)
Fig. 1: Identifying Radio Connector Pin Assignment

Check pin assignment
If the pin assignment is the same as listed in the table above, it is not necessary to install the adapter
wiring harness and CAN bus adapter when installing the Audio 30 APS navigation system.
NOTES ON TELEPHONE OPERATION WITH AUDIO 30 APS NAVIGATION SYSTEM - AH82.61-P-0001-06A

Vehicles with telephone code 316 or 317 can be retrofitted with an Audio 30 APS navigation system.
Ensure that the Audio 30 APS navigation system is a unit with part number A 208 820.....Older units with part
number A 168 820 .. .. are not capable of assuming the master function in the D2B- ring.

The Audio 30 APS does not have a number pad. For this reason, it is not possible to control the telephone over
the radio (see operating instructions).
On vehicles (as of approx. 07.99) with multifunction steering wheel (telephone control with keys on steering
wheel) this function is then also possible with the Audio 30 APS navigation system.

Models 129, 140, 163, 168, 170, 202, 208, 210


Customer information, installation position for GPS antenna
There are two different installation locations for the GSP antenna:
1. Standard GPS antenna from DaimlerChrysler on roof or trunk lid. This version offers the best reception
and is therefore preferable.
2. Use of magnetic antenna in vehicle passenger compartment. This version is part of the kit from the
Becker company and installation is described in Becker installation instructions.
Notes on installation of Becker GPS antenna
The GPS antenna can only be installed horizontally with a maximum deviation of 10° from horizontal.
The GPS antenna should always have an unobstructed view of the sky. Tinted windows can reduce the function
of the GPS antenna considerably.
When installing the GPS antenna always ensure that the arched surface of the antenna points upwards.
