Reason for block

Complaint:
The Audio/COMAND display (A40/8) of the Becker MAP Pilot continuously or intermittently shows the message "No
navigation module connected". This message appears even though the navigation module (A2/30) is correctly locked
in the bracket (A2/30-1) in the glove box.

Cause:
1.) Software in navigation module (A2/30).
2.) The tightening torque of the threaded connection between the bracket (A2/30-1) and the glove box is too high (see
attachment).
This leads to mechanical stress between the bracket (A2/30-1) and the navigation module (A2/30).
3.) The LVDS (low voltage differential signal} line is not correctly plugged in at the radio (A2) or at the bracket
(A2/30-1).
Note on 3.l:
- In vehicles up to and including model year 2012 (code 802), no fault code is logged in the radio (A2); the color of the
connector at the radio (A2) is blue (see attachment).
- In vehicles as of model year 2013 (code 803), the fault code 953B is Jogged in the radio (A2); the color of the
connector at the radio (A2) is green.

c) Update firmware to version R22.3.1205 (available since Week 37/12) or higher using Becker Content Manager.
Notes:
1.) The software versions in the navigation module (A2/30) can be determined from the control unit log and via the
Becker Content Manager (see attachment).
The updates of the navigation software (PND software) and firmware must be performed using the current Becker
Content Manager. The checks for updates on launching the Becker Content Manager must be activated in the "Settings" menu (see attachment). To update the navigation software, it may be necessary to perform a free-of-charge update of the map data at the same time. Detailed information can be found at www.beckermappilot.com. The update
process can take up to several hours depending on your Internet connection.
2.) Remove bracket (A2/30-1) and reinstall without stress:
Note:
The maximum permissible torque is
- 1.7 Nm for models 172 and 204.0, 204.2 and 204.3,
- 2.5 Nm for models 117, 156, 166, 176, 204.9, 207, 212, 218, 242 and 246.
3.) In vehicles up to and including model year 2012 (code 802) and in vehicles as of model year 2013 (code 803) with
fault code 953B, remove the radio (A2) and check the LVDS (low voltage differential signal) line for correct engagement at the radio (A2) and at the bracket (A2/30-1 ).
Note:
Do not replace the radio (A2)
