CD-changer problem
I´m a newbie from Germany, so excuse my English.
Since April I´m owner of a 99 C5 Coupe colored torch red. I have a lot of fun with this car.
But now I have a cd-changer problem and unfortunately no owners manual. The type of it is Pioneer CDX M2016. The cd´s in the magazine are correctly shown in the radio display (e.g. disc 1 track 8). But the cd doesn´t start and err occurs.
I installed another one and the fault is the same.
What can I do?
Thanks in advance !

sorry about the missing information !
I installed another cd-changer which is the same type and another cd cartridge. I tried CD-R, CD+R and original CD´s, none of them worked.
Do you have any ideas ?

in the meantime my CD-Changer problem changed into DELCO-Radio problem. My CD-Changer works right definitly. The problem seems to be with the radio.
Does anyone know if I can read out the current Theftlock-code?
Unfortunately I don´t know the code and I have to disconnect the radio from batterie power for 30 seconds to reset the communication between radio and CD-changer.
I´m afraid that the radio will not work anymore after that
Thanks
Markus


This was posted a while ago by another Forum member. It works if you can access 1-800 numbers from Germany:
The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode NOT in INOP mode. Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Y2K Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere). Procedure: 01. Turn the ignition ON (The radio displays LOC) 02. Hold down the Radio Presets 2 and 3 buttons for six seconds 03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step. 04. Press the AM/FM button 05. The radio display changes to another three-digit number. Write this number to the right of the first one. 06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05 07. Call 1 800 537 5140 08. Press 1 then # (pound). You’ll hear “Invalid Code, try again” 09. Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start) 10. Enter the number from STEP 6 then * (star) 11. Listen to the four-digit number and write it down. It will be repeated twice 12. Turn the ignition ON (The radio displays LOC) 13. Use the MN and HR buttons to enter the code from STEP 11 14. Press the AM/FM button. The radio display changes to SEC Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction on page 3-27 in your Y2K Owner’s manual. Use the code from STEP 11 instead of your personal code. Note: This tip originated from LOTZAHP, Austin TX (credit must be given where credit is due). I verified it on an Y2K C5 with a locked radio - mine.
thank you for your detailed response.
I disconnected the radio from power for about 30 seconds.
After reconnection it still worked. All I had to do was setting the clock.
That should be normal.
Thanks again and have a
