Radio Security Code and Programming/Service Mode
The "Radio Code" is an antitheft device. If someone steals the radio the code must be entered to activate the radio. Likewise, if the car's battery goes dead or is disconnected for safety reasons during service the radio will prompt you to enter the code when power is re-applied.
The radio will display:
CODE - - - - -
Enter the 5-digit Radio Code using the radios preset buttons. This number also appears on your Radio Code card assuming you have one.
After entering the fifth digit press the > button and the radio will activate. Any presets you had before the power loss will return. Apparently a capacitor in the radio holds that information.
To retrieve your radio's serial number without removing it from the dash. Enter the radio's programming/service mode. To do this, turn on the radio then, hold down the M button on the left lower portion of the radio's faceplate for about 10 seconds. The display will change to the radio's serial number. To scroll through the various displays press the + button on the left upper portion of the radio. To get out of programming/service mode turn the radio off by pressing the volume control.
The following information is not in the radio owner's manual.
When in programming/service mode you can scroll through a variety of displays. The only display of any real importance is the GAL. There is no information about GAL in the owner's manual. Please read below.
The following displays are available:
SN 19941629 - appears on the Radio Code card
GI 45
GAL 4
HI 321403
> SIM 111100D
> SIP 141401
Station Signal Strength is Displayed
DSP 0 V 00
AREA USA

AF MAN
########### (blank display - see explanation below)
Explanations of Radio Display Symbols
SN is the serial number of the radio itself needed to get the Radio Code if you lose the card. Contact a BMW dealer, tell them the radio serial number and show your registration. They will get your code from their computer
GI - no idea
GAL (adjustable 1,2,3,4,5,6 using radio preset buttons). This sets the speed sensitive volume control. The higher the number the loader the radio volume automatically becomes as you hit 40mph. It compensates for wind noise due to the top being down. When you slow to below 40mph it returns to your original (idle) setting. I have used it as high as 5 in summer and turned it down to 4 in winter when the top is up. Set to best meet your needs.
HI - no idea. When in this mode pressing the >arrow the display changes to
SIM - no idea - push > again and it changes to
SIP - no idea
Station signal strength is displayed - you can change the station and the display will show you the signal strength of that station.
DSP probably means Dolby Surround Processing, or Digital Signal Processor, DSP does not apply to this model radio in a Z3.
AREA is adjusted using the preset button 1. Area refers to the country where the radio is to be used. Pressing preset button 1 scrolls through the following options; USA, Canada, OC+RDS (no idea), Japan, NO AREA, Europe. Note, the tuning increments change based on the country. In the USA, all FM frequencies end in odd numbers i.e.: 101.5 and 98.7. I other countries FM and AM increments are different.
VIEW (adjustable 1,2,3,4 using the preset buttons) 3 is brightest other than that I have no idea.
AF Auto (something)? Well, I know it doesn't stand for Auto Focus.
########### Blank display used to test the LEDs. By pressing radio presets 1, 2, 3, 4 the display scrolls through a set of patterns so that any bad LEDs are easy to see.

the Best way to explain this is once you have your security release code, you just type in the code regardless of what comes up on the screen. You usually have 3 attempts. so for example if your code is 12345. You input this via the radio number buttons corresponding to your code usually on the bottom of your stereo next to the scan buttons. you usually have the number 1 displayed on your radio screen ( signifying your first attempt.) Just input the security code corresponding to your radio number key pad, do this like inputting your ATM pin number, no breaks, you don't have to press enter just do it continuously ie 12345 and once done press the Right Arrow button ie usually your volume control button > ( Mine has a big button that has this printed on it =
You will have to go to the dealer to get the reset code and instructions. It will be unique to your particular radio.
If your radio is locked and needs to be unlocked, it would require a security code versus a radio code.
The security codes for each radio are unique. There will be a card with the number in the original manual supplied with the vehicle when purchased new. There you will also find the procedure for unlocking the radio. If you do not have the original card containing the code you may go to your nearest Mercedes Benz dealer with I.d and proof of ownership of the vehicle and they will be able to get the code and tell you the procedure.
whats number do i put in to unlock radio is it security code or radio code to unlock radio?
With the radio presets
If the radio has a security code you will have to insert the code for the radio to work.
where is radio security code located for a 2005 ml 350 mercedes
What worked for me was to unplug the antenna in the back of the radio and then enter the security code. Once the security code is entered, you can plug the antenna connector back into the radio.
Never knew that there was a security code for the radio, just set the stations etc.
The radio unit will need the security code If you disconnect the battery from your vehicle. The radio will reset, thinking it was stolen out of the car, and will require the security code before it will work again.
Howdo i reset my radio security code ml 500 2002
