Volkswagen Passat 2011 Workshop Manual page 27

After disconnecting the radio navigation system's voltage supply,
system operation is restored when reconnecting the voltage sup‐
ply without entering the code number. The prerequisites are that
initial activation of the anti-theft coding has been performed and
the radio navigation system is reconnected in the same vehicle.
A blocked radio navigation system can only be returned to normal
operation by entering the correct code number for the anti-theft
coding.
The anti-theft code can be determined using ⇒ Vehicle diagnostic
tester. The radio card used in the past and the sticker on the radio
have been discontinued.
Note
To determine the anti-theft code, the ⇒ Vehicle diagnostic tester
must have an "online" connection (network connection), and the
user must be authorised to use the program to retrieve radio co‐
des.
Determining anti-theft code of anti-theft coding via vehicle diag‐
nostic tester:
Special tools and workshop equipment required
♦ ⇒ Vehicle diagnostic tester
On ⇒ Vehicle diagnostic tester, select "Guided Functions".
or
On ⇒ Vehicle diagnostic tester, select "Guided Fault Finding".
For adaption, use "Retrieving radio code" function.
Your system rights are then determined. The operating data, the
VIN and the unit number of the radio or radio/navigation system
are then read out automatically.
Note
When installing radios or radio navigation systems which are new
or have not yet been adapted to the vehicle, it may occur that the
tester is unable to read out the unit number of the radio or the
radio navigation system. In this case, please enter the unit num‐
ber manually. It can be found on the sticker affixed to the unit and
is also stamped onto the side of the unit.
The radio code which has been determined is then shown on the
tester's display.
The anti-theft code must be entered in the radio manually.
Deactivating anti-theft coding:
– Enter the previously determined radio code with the "RNS 510"
number block shown on the display and confirm the entry.
The unit will be released and is ready for use.
