1) Turn on radio and the radio display shows "SAFE", thus the problem.

2) Press the P.Scan and RBDS buttons simultaneously (at the same time) and hold until "1000" is displayed. Release the buttons but Do NOT press buttons again as the radio will think the "1000" is the code.

3) Use Preset buttons 1 through 4 to enter the four-digit code number from your radio card that you got when you bought the car. Preset button 1 corresponds to the first digit, preset button 2 corresponds to the second digit, and so on and so on.

4) Once the code shown on the display is correct you must press the P.Scan and RBDS buttons simultaneously and hold until the word "SAFE" appears in the display again. Once the word "SAFE" appears you can release the buttons.

4) The radio should unlock and be available shortly afterwards.

5) 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.

6) If you lose your radio code, contact your Audi dealer as you are SOL.

Yes you can. Nothing goes together better than an iPod and a TT.

The basic way of course is to get a tape adapter and connect it to the stereo that way. You will not get the bast sound but it will work.

The other option would be to get a mini jack installed in the back of your head unit. Jeff Bipes used to this on many TTs and it worked great.

Tod adds "You could also get an FM transponder, and it would eliminate any wires." 3/26/2005

Aren updates "The best way (Sound Quality wise) to do it is to avoid using the headphone amplifier's output jack. Use a dock connector to utilize the line level output into a proper amplifier (like a head unit with an aux in). There are plenty of kits to dock your ipod and have it mimic a CD changer, and also some head units that will display the ipod info for searching & playing..." - 1/30/2006

David adds "My 2006 TT equipped with an Audi Concert radio (single disc CD) and XM radio apparently can't accommodate an iPod, according to my local installer. One company working on it (Metra at www.wire-tunes.com) via a device called "Axxess" but this morning, said it can't yet be done. The built-in XM radio of the Concert seems to be the sticking point." - 3/6/2006

The Concert radio can be coded for two different Bass/Treble Vehicle-specific tone control slopes. One is for Bose/Concert and the other for Concert only. You can change this setting by recoding the radio module with either a VAG1151/1552 or VWTOOL. The standard coding for a TT w/bose and secondary display is 00517. If you don't have a cd changer, secondary display, etc. this value may vary in the first decimal place (see page 5 of audi tech document on adding a CD-Changer for complete details. URL at end). We are only concerned with the value at the second decimal place (in the example above it is 1 for Bose tone slope). If you have the radio recoded and change the 1 to a 0 (zero), you will enable the other Vehicle-specific tone control.

Once the radio is recoded you will notice the "Bose" missing from the display on powerup. The Bass/Treble range is now +-6 but the adjustment is more dramatic.

I must say, the effect on the Bass is incredible! It may not be a "true" sound in the Bose universe but many will find it an improvement.

Paul adds: "I changed the code in my old TT 4 years ago and the extra boost I got from the bass was superb. I have bought a new TT and need the code again (I have unfortunately forgotten it). Are you saying that the code (in the case of Bose/Concert with CD changer) should be changed from 00517 to 00507? - 4/2/2004
