Well, it might seem obvious but you need to input the code which on my Volvo 850 is a four digit number. I'm assuming this is a used car, so you need to get the code from the previous owner, or if this is not possible, contact the manufacturer directly to see if they can help you. Good luck.

How to insert the code for the radio of my golf3 /1996



ENTERING SECURITY CODE

Most vehicles are equipped with Heidelberg V or VI radios that are equipped with a theft protection program. When the battery has been is disconnected or if the radio has been removed, the radio will lock-up electronically and cannot be operated until the security code is entered. On the Heidelberg V, if the proper code is not entered in six attempts, the radio will lock-up permanently and cannot be repaired. On the Heidelberg VI, two incorrect attempts will lock the radio for about 1 hour.
The Heidelberg V may have a code assigned at the factory or a personal code created by the owner. The Hiedelberg VI has a code assigned at the factory and entered by the dealer during pre-delivery inspection. New radios come with the code printed on a sticker but not entered into memory. All codes are 4 digits. To code the radio:
Heidelberg V

  1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
  2. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear for about 3 seconds, then the display will go blank. Release the buttons then.


NOTE If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.
  1. Use the first four station selector buttons to enter the code. The first digit of the code is always 1. Each time the other buttons are pushed, the number in that position will change.
  2. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When the radio plays and displays a frequency, release the buttons.
  3. If the code was entered incorrectly three times, momentarily disconnect the battery and try again. If the code is entered incorrectly three more times, the radio cannot be coded and cannot be repaired.

  3. If the code was entered incorrectly two times, leave the radio ON for one hour and try again. This can be repeated as often as required.

Code radio


In the owners maunel you should have a card with the radio code on it.

The radio will only display EEE or OFF when the wrong code has been entered and the radio is locked depending on model - this is due to the battery being disconnected and the incorrect radio code being entered 3 times. You will neet to reset the radio. To do this the radio has to be on for either 2 or 4 hours - see the manual for your model. If you got the code from a card from Volvo, and it didn't work, then the radio has been changed or it has been reset by the dealer and your current code is invalid. You will have to pull the radio and find the serial & model number, and get Volvo to look up the code for that radio or the dealer may be able to lookup the radio code via vin# from Volvo. The dealer can reset the radio and enter a new code. When the radio is "ready" to accept an unlock code the display will say "codE". You will need this code if your battery is ever disconnected.

Landrover cassette display appear "SAFE" This cassette model is XQE500550.How can fix safe mode.


If you have the correct radio code for the unit, just wait about an hour with the power on in the radio. The screen will eventually display (code) or (enter code) follow the directions in your radio manual to enter the code and the radio will be operational again. The safe mode is on because either the radio fuse blew, the battery was too low on charge or the radio was momentarilly disconnected from it's power source. Most common is low battery voltage. Charge your vehicle battery, locate the radio code, wait till radio displays CODE and enter the code an have happy tunes again.
