hold rbds and pscan till you see numbers then use the radio memory buttons to control the number you want to put in after the numbers are put in hold rbds pscan again till u see it says safe and radio works.

THIS WAS POSTED ON THE AUDI TT CLUB WEB SITE.

Turn on the radio. The word "SAFE" appears on the display.

* Press the FM2 and RDS buttons simultaneously and hold them down until "1000" lights up in the display. Release buttons. Do not, under any circumstances, continue holding them down or press them once again. This would cause the radio to consider the number "1000" to be the input code number.

Use stations buttons 1 - 4 to enter the code number on your Radio Card.( THE RADIO CODE SHOULD BE WITH THE OWNERS MANUAL-??) Use button 1 to enter the first digit of the code number, button 2 to enter the second digit, and so on. Station buttons 5 and 6 cannot be used.

* Once the code is shown in the display, press the FM2 and RDS buttons again simultaneously and hold them down until the word "SAFE" appears on the display. Soon afterwards, a frequency will be displayed.

(If you do not have the "Radio Code", the Audi dealer, or someone, will have to pull the radio out to get the serial number off of the back.)

The radio can now be used again.
