Procedure for entering radio code

Recommended Posts

Hi all.

The previous owner of my 928 swears I have the correct radio (CR-210) code: 1224. When I tried to enter it in place of the C O D E message, the 1 kept blinking, but no radio started. After a few tries, I began punching other buttons. "WAIT" appeared in the window, and nothing will get rid of it, not even disconnecting/reconnecting the battery, removing/replacing the radio face plate. Of course no buttons operate. I tried the press-and-hold-TP-for-30-seconds thing, the press-the-tone-button-then-8-&-0-together thing. Nothing happens at all. There are no numbers above the buttons, so I don't even know which ones are 8 and 0.

What should I do?

(What should I have done?)

Any help will be greatly appreciated.

From the CR-210 Owners Manual (which you can download here)...

"This radio renders itself inoperative in the case of theft. If the

radio or car battery is disconnected, the radio automatically

disables itself. Once the radio is reinstalled or the battery is

reconnected, the word "CODE", with a flashing letter "C", and the

digits 1-0 appear in the display. Prior to use, the correct code

must be entered via the multifunction keys.

Example: CODE 1530 (Preassigned to each radio and supplied

to the owner on the PORSCHE RADIO CODE CARD) is entered

by pressing the multifunction keys in sequence. (See diagram.)

After the first digit is entered, the word "CODE" disappears and

the number is displayed followed by three dashes. As digits are

entered, the next line in sequence flashes. When all four numbers

have been entered, the first digit flashes. At this time you can

overwrite the code as often as necessary. To correct any error,

you must enter the complete code. Once the correct code is

displayed, enter by pushing the signal seek switch.

If you have entered an incorrect code, the word "CODE"

reappears in the display. The system allows two more attempts

for a total of three. After three incorrect attempts, "WAIT" is

displayed. A ten-minute time interval must lapse before you can

attempt the coding process. You have three more attempts to

enter the proper code at this time. After nine attempts at code

entry and three waiting periods of ten minutes each, the radio will

"WAIT" for sixty minutes. After sixty minutes, you will have three

more attempts at code entry. Should you fail at this point, "WAIT"

will appear, and sixty minutes must pass before you can make

another attempt.

Attention: The radio must be on during the waiting period.

Note: The RADIO CODE CARD and window decals are supplied

with the vehicle. To avoid unauthorized use, do not leave the

RADIO CODE CARD in the car!"
