does radio allow you to tune to stations number ?
if it does but it won't stay there for more than 30 seconds radio is telling you that station is not sending a strong enough signal out for radio to properly recieve it ,also ck roof antenna for damage automatic car washes kill these all the time

won't allow you to tune it there no way, then radio is in parental control mode obtain code and reinstate station permission read owners manual for this feature

Please check the information that came along with the owner's manual. It should be printed on a card that comes with those booklets. I assume you've already done that though. I've attached the procedure for entering the code below. Let me know if you have any trouble with it.

If the radio is disconnected from the power supply it is not ready for operation when reconnected. After switching on the ignition and the radio the word "CODE" appears on the display and the letter "C" flashes.

NOTE: The five-digit code number for this radio is printed on the CODE CARD which you were given.

Enter the code number with station buttons, e.g. number 1, station button 1.

After entering the first digit the word "CODE" disappears and the digit entered is displayed followed by 4 dashes. The next digit to be entered flashes. After all 5 digits are entered, the first digit flashes again. In this state the code number can be written over repeatedly. A correction can be made only by reentering the entire code number.
Confirming the code number: Press seek-UP/seek-DOWN or SCAN button. The radio switches on automatically and displays the station or frequency stored for station button 1.

If the wrong code number has been entered and confirmed, the word "CODE" appears on the display again. After the code has been entered three times incorrectly the word "WAIT" appears on the display and the radio is disabled for approx. 10 min .

NOTE: The waiting time continues to run only when the radio is switched on.

After expiration of the waiting time the word "CODE" appears on the display again and the correct code number can be entered. After 3 more incorrect entries the radio is again disabled for 10 min . After 3 more incorrect entries (a total of 9 incorrect entries) the waiting time is increased to 60 min . After 3 more incorrect entries the radio locks up again for 60 min .

Then turn the ADJ knob to increase or todecrease. To set the minutes, press the clock button again. The minute numbers will flash. Then turn the ADJ knob to increase or to decrease. The time can be set with the ignition on or off.
With RDS: Same as without RDS unless you want to Sync. with a radio station. To synchronize the time with an FM station broadcasting Radio Data System (RDS) information, press and hold the clock button to enter the clock set mode, then press and hold the clock button for three seconds until UPDATED appears on the display. If the time is not available from the station, NO UPDATE will appear on the display. RDS time is broadcast once a minute. After tuning to an RDS broadcast station, it may take a few minutes for the time to update

1. If the radio is disconnected from the power supply, it cannot be operated by simply reconnecting. After switching on the ignition and the radio the word "CODE" appears in the display on the radio.
2. The code number for the radio is given on the enclosed CODE CARD.
3. Enter the code number with the station button, e.g. number 1, station button 1. After entering the first number the word "CODE" disappears and the number entered appears followed by 4 dashes. The next character to be entered flashes. After entering all five numbers, the first character starts flashing again. In this state the code number can be written over as frequently as desired. A correction can be made only by entering the complete code number again.
4. Confirm code number: Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio station or frequency stored with station button 1.
5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up for approx. 10 min. If the code is entered incorrectly three times again the radio locks up again for 10 min. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 min. Another three incorrect entries lock up the radio for another 60 min. The waiting time runs only when the radio is switched on.

You have a failed output section inside the radio. If you remove the radio, and take it apart, you will see some burnt capacitors at the very back side of the PC board. This is, unfortunatly, a very common problem with those cars. You are going to have to get another radio, the expense for the manufacturer to fix is is more expense than a replacement. Sorry, but I have seen this situation too many times.

the 4 digit code will be entered using the preset station buttons(1st code digit=1st station button,2nd digit=2nd button),enter all four digits and radio should come on,if after 4th digit radio does not play press cd button on unit-(make sure the display on the radio does not read off-if it does, it is in anti-theft mode

Check for blown fuses

I would look for a ground that is inadequate.
If any part of this is operating essentially without shielding due to a bad ground, then cell towers, a radio or TV station transmitter, CBs, land mobile radio, amateur radio - any of these can inject enough signal to drive modern electronics completely bananas.
The onboard electronics used for just about everything that is remotely controlled by switches generates a ton of digital garbage and can interfere with anything.

The kind of problem you are experiencing started when we stopped using vacuum tubes 50 years ago operating at high voltages and started using semiconductors that use much lower voltages.

A tech with a common multimeter should be able to locate the missing ground connection without too much trouble.
