Hi-
I just got a 2013 Sprinter with a sound 5 radio. I put in the cable as described in this forum as I did on my 2008 Sprinter and found that there was no aux option as others have described. After making an appointment with the dealer for next week, I found the instructions below on this website:
http://www.mercedes.gen.in/WP35/mercedes-benz-sound-5-ha1111-hidden-test-mode-menu/
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. 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.
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. 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. 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.
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. I have made a listing of the available headings within the test mode scroll adding notation to the individual settings if known.
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. 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. You will also notice some of the listed options may or may not be available in the Becker model. (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. However you may find different options are available to you once you enter the Test Mode menu on your own set)
Have fun…..
”Switch the radio on without the ignition on, and turn to radio function. Switch off…..then turn radio on again, after 2 sec. press the sound adjustment key (with the 2 notes on it) together with the #4 selector for radio stations. 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(on) 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 !!!!!”
Here is my Gen-In video of how to access the TEST MODE adopted from the above information that worked fine for me.

My aux is now working, and I have cancelled my dealer appointment. Good luck,
