Meantime if you get anywhere before I do please let me know your findings. I will have to dig out my spare set and fire it up and see what happens.
Mercedes w203 radio diagnosis upgrade#
This mentions an amplifier mounted under the front seat and extra speakers I assumed upgrade available for all head options. At least that’s how I understand the text. There is reference to an upgrade speaker system for the Vito and you would imagine you could specify it for either radio head unit. Did you try these pin outs for the yellow connector?: Having assumed, like you, that as the pins were there and the radio option available in the menu, I do kind of find it strange that it does not give at least RCA audio level outputs. I must admit I don’t know the answer to your question regarding the low level audio output. WB– USA Weather Band Selection Option ON OFF UKW is “Ultrakurzwelle”, German for Ultra Short Wave, or FM (87.5 – 108MHz) KW is “Kurzwelle”, German for Short Wave (18.5m – 50m)
MW is “Mittelwelle”, German for Middle Wave, or AM (185m – 580m) LW is “Langwelle”, German for Long Wave (700m – 2000m) LW– Long Wave Band Selection option ON OFF KW– Short Wave Band Selection option ON OFF (I assume this is SW option see below German radio band translation) TP VOL – RDS Traffic program break in volume level GAL 7 – Volume adjustment set to activate at higher speeds GAL 1 – Volume adjustment set to activate at lower speeds GAL OFF – No speed dependent volume adjustment This compensates for higher noise levels at increased speeds. GAL is a special circuit which automatically adjusts the radio volume according to vehicle speed. PRD – Production Date – /DAY/MONTH/YEAR (DD/MM/YY)

SW – Software Date /Week and Year/ (WW/YY)ĭECK – CD Deck Date /DAY/MONTH/YEAR/VERSION (DD/MM/YY/VV) HW – Hardware Date /Week and Year/ (WW/YY) I have taken a ‘first guess’ at what the individual settings mean or relate to – I may be wrong in some cases and there are a few I haven’t worked out yet but hopefully it will provide the basics to go on should you venture into this menu and wish to make some changes.

Here is my Gen-In video of how to access the TEST MODE adopted from the above information that worked fine for me. this puts you into the menu of the radios AUX EXT……press the button up key until you see the AUX OFF….turn the volume dial till it says AUX EXT….then press left key to finish…….now press CD twice and you should see that button now has two options in the display…….NOW THE AUX IS ACTIVE !!!!!” press the sound adjustment key (with the 2 notes on it) together with the #4 selector for radio stations.
Switch off….then turn radio on again, after 2 sec. ”Switch the radio on without the ignition on, and turn to radio function. However you may find different options are available to you once you enter the Test Mode menu on your own set) (I have found that some EU Becker models do not seem to have the WB USA Weather Band option and also the CD Temperature warning is set at ‘0’ and appears not to function enabled in these versions. You will also notice some of the listed options may or may not be available in the Becker model. Please note that if your radio is the Becker Audio 5 NG BE9012 your test mode menu does not display ‘Test Mode’ when first entered, it just displays ‘SOUND 5’ From here you can then scroll through the menu selection as below. There are a few options that I am yet to fully understand but it should give most readers a general insight into ‘what-does-what’ and the meaning of some of the info displayed within. I have made a listing of the available headings within the test mode scroll adding notation to the individual settings if known. Mark’s original instructions are posted below along with a video that I made to show how to access the Test Mode and what was available once selected.

Response to this post has highlighted that there is a possibility current radios of this model (Model years 2012/2013-on) have the manual ‘front panel’ test mode disabled – Sadly if this is the case, you will have to take a trip to your dealer to have your chosen functions enabled via MB Star. Thanks again for this Mark ! There are other interesting options available to access through this menu too that I hope to investigate further given time. Thanks to a reader of the original post (Mark) who discovered a manual way of activating the AUX mode through access to the radios hidden ‘Test Mode’ without using the MB Star dealer setup. What had been assumed at the time of writing was that the radio could only be activated to allow this option using the MB dealer STAR plug in diagnostic tool. The Mercedes Sound 5 radio/cd Mobis HA1111 unit fitted to later Vito and Sprinter models has the ability to handle external wired audio input and can be modified as shown in this earlier post.
