First of all be sure that your four digit security radio code is correct. If you had attempted three times without success to exit from safe mode by inserting the code, radio is blocked in safe mode for a while. Now turn ON the radio (in safe mode), and let it turned ON for one hour, then follow this procedure.
The sequence of VW radio gamma programming is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
For example: we have the security code "5079". Then:
3. By the no.# 1 key you will set up the first safe code digit. Push 5 times on the no.# 1 button. The "5" number will be setted.
4. By the no.# 2 key you will set up the second safe code digit. Push 10 times on the no.# 2 button. The "0" number will be setted.
5. By the no.# 3 key you will set up the third safe code digit. Push 7 times on the no.# 3 button. The "7" number will be setted.
6. By the no.# 4 key you will set up the four-th safe code digit. Push 9 times on the no.# 4 button. The "9" number will be setted.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed.
The radio is now ready for use!

IMPORTANT NOTE: You must have the security anti-theft code for your Audi radio from the car manufacturer, or from an Audi dealer!

Entering Anti-theft Code

The following is the procedure to re-activate the radio if the display shows "SAFE". It is important that the procedure be followed in the correct order.

1. Turn on radio. The radio display shows "SAFE".
2. Press the FM2 and RDS buttons simultaneously and hold until "1000" shows on the display. Release the buttons. Do NOT press these buttons again, otherwise the radio will consider "1000" to be the code.
3. Use Preset buttons 1 ... 4 to enter the four-digit code number from your radio card. Preset button 1 corresponds to the first digit, Preset button 2 corresponds to the second digit, etc. Each press of the button increments the number by 1.
4. Once the code shown on the display is correct, press the FM2 and RDS buttons simultaneously and hold until the word "SAFE" appears in the display, then release the buttons.
5. The radio should unlock and be usable shortly afterwards.
6. If an incorrect code is entered, the word "SAFE" appears, first flashing and then continuously. You can repeat the above steps to unlock the radio once more, the number of attempts will be shown in the display. If an incorrect code is entered again, you radio will be locked for about one hour. After one hour - the radio must stay on and the key must remain in the ignition lock - if the display goes out, the you can repeat the above procedure to unlock again. The cycle - two attempts, one hour lock-up - still applies.
7. If you lose your radio code, contact your Audi dealer.

Note: Some European market Concert radios have a TP button instead of the FM2 button, so the description above with those units would require pressing the TP and the RDS buttons simultaneously.
