  • From Mark on Mercedes Sound 5 Auxillary Audio Input Modification

    I found the solution to the problem, 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 untill 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 !!!!!

    You don´t need to visit Mercedes for a STAR fix !!!!

    Good luck !

      Hi Mark,

      Thanks for the useful info, what I think you may have actually done there is selected the function AUX ON as described in the manual page photo shown in the post. Only radios ‘enabled’ with the AUX function have access to turn this on – yours obviously has. The HA1111 radio with a standard flash has no AUX ON – AUX OFF option and it will not appear anywhere, even in the set up menu. In some cases even CDC (disc changer) cannot be selected unless enabled in the radio’s flash. You may be fortunate that your radio is already configured to allow the extra options to be selected, some sets are not.

      I will test out your solution with a radio known to be without AUX that I have here and report back on the blog. I hope you are correct as that’s a great work round and will save folks a fortune at the dealers. Thanks again for the informative input.

      All the best
      Steve.

        Mark – That’s an absolute GEM !!!

        From testing out the known featureless set I have here and following your instructions It it does in fact reveal a hidden manufacturer ‘test mode’ within the radio itself, (how on earth did you discover that !!) In this test mode there is indeed a selection for turning the AUX – ON and OFF. That is a fantastic find and for that I truly thank you. I will put together a video later this evening on how to access this menu and show what else is hidden in there too ! (some real interesting stuff hidden in there!! eg turning the Weather Band – ‘WB’ reception option on or off, LW or MW enable/disable and a few other interesting features )

        Its opened up a whole new avenue to accessing the radio, its functionality and how it now can be ‘user’ configured without STAR – not just with AUX selection, but with a multitude of other options too. Thanks again for letting me know and sharing this top find on the blog.

        Look out for the video in the next day or two credited to your findings….

        All the best Steve

          Unfortunately this trick doesn’t work on every set; mine at least didn’t work;

          so I take an appointment at my dealer, and solved the problems;
          looks like test menu is not enabled by default in newer sets (mine is 2013) at least not in Canada; and he didn’t want to enable for me;
          but at least he enabled all featured missing from initial set-up: Aux, RDS (after 15 min of hard explaination to the mechanic that RDS is not the TV Sport Channel we have in Montreal, it’s just a radio function 🙂 )WB, LW, Traffic announcement, actually I was staying just beside him to have him checking ON option for all features on his software.

          BTW his software is quite a piece; once connected he knew everything about what I do with the car.

          thanks all for every answer; I learned a lot.

            Hi Cat,

            At least now you have it sorted out… eventually. We all know why he would not enable manual test mode for you don’t we? – He would not get any monetary return for future work if you could change things yourself! It is interesting that the radio was not ‘Test Mode’ enabled. It’s worked on every set I have tried it on thus far, although I will admit that the manufacturing date of the radios tested would not extend much beyond 2010. Maybe this is a point to note.
            Thanks again for the useful feedback.
            All the best

            Steve

        • From Cat on Mercedes Sound 5 Auxillary Audio Input Modification

          could this trick, by any chance, to enable the RDS function?
          can someone please check in that well hidden menu?

            From Steve Ball on Mercedes Sound 5 Auxillary Audio Input Modification

            Hi Cat,
            I did have a quick scroll round the test mode menus and unless I am mistaken there is no mention of RDS On or Off, I suppose it could be a region setting but at this moment I am still unsure. Let me have another look over the next few days and I will report back. Part of me still thinks that if the RDS function cannot be selected as per the manual it is possibly faulty. What did the dealer suggest? I realise you are not impressed with your local dealer but why not use the larger network of dealers to get some answers, its a Mercedes after all and no matter where it was purchased the support should still be there from any dealer. Maybe try calling the next county dealership on the phone to start.

            Let me know and I will get back to you when I find out a little more about the test menu.

            Regards Steve

            Cat,
            The RDS Mode ON/OFF is inside the test mode menu ! Enter the test mode as described above and find the RDS option, when you have it rotate the volume control to select ‘ON’ and then advance through the remainder of the menus using the up button until you reach END, then turn off the set. You should now have RDS enabled.

            Regards Steve

    Hi, I just bought a new Sprinter, 2013, and I can not turn on RDS function on stock radio.
    Eben in the books are written as available, looks like the radio doesn’t have this function.

    is that true? in no rds what other radio I can use to replace the stock radio, to have RDS and bluetooth?

    thanks

    • Steve Ball

      From Steve Ball on Mercedes Sound 5 Auxillary Audio Input Modification

      Hi There,

      I am not sure if they missed it from the new edition manual for the Sound 5, but the slightly older published radio operation paperwork shows that a continuous press on the ‘FM’ button top left will turn RDS on/off. Look here: Look specifically at .pdf page number 12. Not sure about the Bluetooth but a call to the dealer will confirm your options here if you radio/vehicle is pre-wired with the phone option. Hope it works for you.

      Regards Steve

      • From Cat on Mercedes Sound 5 Auxillary Audio Input Modification

        yes, I saw and try that, but nothing happened.
        I press it for about 30 sec and still nothing, not even a beep.
        is maybe another combination: press FM and turn the volume, or something like that?

        just asking, I would really want it to turn RDS on.

          Hi again,

          It seems the mute button (speaker symbol with a line thru) has a similar function if pressed and held, it should also turn RDS on and off according to the manual. Worth a go, maybe this will work. Failing that I am stumped !! Let me know how you get on.

          Regards Steve

          • From Cat on Mercedes Sound 5 Auxillary Audio Input Modification

            hi there, sorry for the delay;
            unfortunately it not working either; tried lot of combination with mute and other sound button;
            looks like I have to visit the dealer; I already hate them

  • From CHRIS on Mercedes Sound 5 Auxillary Audio Input Modification

    HELLO, I RECENTLY BOUGHT A W169 2006.THE CANR WAS INITIALLY INSTALLED WITH THE RADIO CD 20 I BELIEVE. THE PREVOIUS OWNER REPLACED IT WITH A PIONEER USB RADIO CD. THIS IS NOT FINCTIONING WITH THE MULTIFUNCTION STEERING WHEEL.ALSO THE WATCH IS NOT SYNCHRONISED. SO I DECIDED TO PURCHASE A MOBIS SOUND 5 NG HA 1111 WHICH SUPPOSE TO BE COMPATIBLE WITH THE A CLASS PLUS OTHE MANUFACTURER MODELS. SOMETHING IS REQUIRED TO GET THE THING FUNCTIONING..ANY IDEAS?
    CHRIS

    • Steve Ball

      From Steve Ball on Mercedes Sound 5 Auxillary Audio Input Modification

      Hi There Chris,

      If I understand your question correctly, am sure the HA1111 is compatible with the A Class Mercedes (2006). I think there should be a small plug and loom (separate to the speaker and power ISO wiring) that plugs into the upper row of radio terminals. This connects to the steering wheel controls through a short loom, via the air bag ‘clock spring’ contact arrangement to the steering wheel controls. There is a chance that if the steering wheel controls were not used with the aftermarket radio the original ‘wheel control’ connector may have fallen down in the dash somewhere. Have a look around and see if you can locate it.

      If you are making reference to the radio not working with regard to ‘PROD’ error then please read again the original post as it explains in detail why and how the PROD error occurs. Please let me know if you need any more information.

      I hope this helps,

      All the best. Steve

      • From CHRIS on Mercedes Sound 5 Auxillary Audio Input Modification

        dear Steve,
        thank you for you reply.Today one mercedes dealer in athens managed to install physically the radio cd but the unit is not functioning due to prod error which ligts after few minutes. i believe that it is needed to reset its flash code in order to have the unit usufull. The technicial cannot do this procedure.

        • Steve Ball

          From Steve Ball on Mercedes Sound 5 Auxillary Audio Input Modification

          Hi Chris,
          As you have discovered the PROD error is caused by a mis-match of the radio and vehicle. The details of this are outlined in the original post as you have no doubt read. The only thing I can suggest is to take your radio to a car audio specialist for decode (reflash) or you can often pick up ‘used decoded’ Sound 5 unit from the popular online auction sites cheaper than the decode operation at the audio specialist!
          Good luck and I hope you get it sorted out quickly.
          Steve

  • From Mike Sommerfield on Mercedes Sound 5 Auxillary Audio Input Modification

    Steve i bought an after market Android media system designed for a Sprinter with Canbus suport and it is replacing a Sound 5 with Canbus ( Iknow because I have a seen a diagnostic laptop system turn on my radio ) on the Sound5 There are the regular speaker connection bank and then only five connections on the lower connect Unfortunatelry the aftermarket unit came with a connector designed for a Radio 20 Which has hot, neg and two can bus wires , I can t find a pin out for the sound five that indcates the canbus pinout just ISO10487 pinouts Are they using what would normally be the power anttena and dash light terminals for the canbus wires and if they are which is high and low ?

    • Steve Ball

      From Steve Ball on Mercedes Sound 5 Auxillary Audio Input Modification

      Hi Mike,

      I see your problem.

      The Sound 5 should have the same pin outs as the earlier Audio 5 as these were fitted to both Sprinter and Vito Models at different points in time. If this is the case I am not sure that the Power Antenna / B+ wires are used for CAN BUS as you suggest. If the wiring is the same on the two models of radio above then this document will help:

      http://www.speedsignal.de/Dokus/342_ADIF/en/342DB01.pdf

      ISO Connector A – Pin 6 = CAN Hi, Pin 7 = CAN Lo, Pin 8 = GROUND. I hope this helps. If not have a search for CAN Adapters and view their documentation as often the wiring to common radios in the Mercedes range is shown.

      Good luck – Steve.

  • From Stu on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

    Hi, I have for ages had a gear selection problem with my 109cdi and every morning from cold it is almost impossible to select 1st gear or reverse. Pulling away and then trying to get second is the same. Once the van warms up the gears are much better but not great.. I have read your article with interest and have taken the step of changing the gear oil with carlube atf-u as you have. Immediately the gear change is smooth. Miracle in my eyes.. Are you a technician or have knowledge as to the suitability of this lubricant. Does your van still run ok using it..
    Would hate to destroy gearbox…I only do lowish mileage as i work around local area as a gas fitter so van doesnt get hammered..Interested in your updates on your experiences of using this oil..Regards

    • Steve Ball

      From Steve Ball on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

      Hi there Stu,
      I am so pleased the oil swap worked for you, to answer your question my own van is still running fine with no ill effects.( I am 99% sure that it will continue that way too!)

      I have a lifetime in engineering background, both automotive and industrial and my own research on oil types has shown that what manufacturers do is select an oil that is good for all uses no matter where their vehicle is in the world. A perfect example is: A van could be sold to a customer in Saudi Arabia who uses his vehicle fully loaded and always tows a laden trailer – the oil must offer the best protection for his type of use. For my use and I would imagine yours, an oil that is almost of the same specification but would probably require an oil cooler in the Saudi case above, will be just fine in the UK – especially if you rarely work the van to its limits.

      Its for this reason that I chose to try the oil swap. In both our cases the gearboxes we have, most certainly are exhibiting a degree of wear and in selecting alternative oils we can continue to use the vehicle without troublesome gear selection problems. In truth our gearboxes may need mechanical repair to rectify the selection problems and return them to factory new condition, all I am suggesting is why not delay this repair (maybe indefinately) by finding a work-round to the problem. My wallet agrees and I would imagine yours does too! Thanks for your comment.

  • From lee on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

    hi how long did you change gear oil just to make sure there are no long term probs ?fanx in advance lee

    • Steve Ball

      From Steve Ball on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

      Hi Lee, It’s been about six weeks now and about 1500 miles without issue. I suppose in real terms it’s not such a long time BUT…

      The fact remains the gearbox must have some fault in the first place (most probably some synchro wear 90k) to not operate correctly with the specified oil and the only permanent fix would be to rebuild / replace the gearbox. What this oil grade swap offers is a way to continue to drive the Vito in a manner that befits the vehicle, nice changes and importantly no baulking first gear engagement which to be honest was nothing short of dangerous at times !

      I have no issue with running the box with ATF synthetic as it is used as standard in many manual transmissions (ford have used it for years) as well as auto’s. It’s a strong and protective oil that is often used with an oil cooler in an auto box situation, if you don’t do a lot of everyday towing or ‘fully laden work’ this is never going to be an issue as in the UK ambient’s are way low anyway. If you are working the Vito hard to its extremes the gearbox really needs to be fixed/replaced at a cost of £1000 + . Personally I prefer £20 and am able to enjoy driving the vehicle again until one day eventually (who knows when!) the mechanical fix is required. I will probably mark this time when the replacement of the clutch is due as it makes most financial and practical sense. This could be a few years down the line from now; I will just wait and see. Who knows it could stay this way, remaining unchanged throughout my ownership and maybe the next!

      • From david on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

        Do you think this will work in a 04 vito? I just bought it and in 2 daysI lost revrse?

        • Steve Ball

          From Steve Ball on Poor First Gear Selection - Manual Gearbox Problem W639 Vito - Cure

          Hi there David,
          Its more likely if you have lost reverse (its probably become increasingly difficult to engage, although if you just bought the van you would not know this) it is the selector mechanism arm that is worn on its pivot on the side of the gearbox. If you can engage reverse easily with the engine off then it could be another internal gearbox problem.

          As the pivot wears it does not allow sufficient ‘pull’ on the lever to actuate the selectors correctly on the gearbox, the extreme left gears – first and reverse – are the ones that suffer poor engagement and indicate such pivot wear. The best bet is to get underneath with a torch and grasp hold of the upper L shaped lever that connects one of the cables to the selector mechanism, if it wobbles considerably on the pivot shaft it should be replaced, this is common wear also seen on sprinters. The gear change cage can be replaced as an assembly without taking out the gearbox. These should be available both used and new, but do check a used one is not as bad as the one you have ! Good luck. Steve

            Sure Mark, Absolutely no problems at all – 6k miles plus since the swap out and it responds just like when I had first done the job.
            Do report back when you have changed the oil. Remember if you keep the oil you drain out you could always swap it back if you desired but I think the results will surprise you!

  • From Andrew Rudge on Mercedes SRS Fault - Fix

    It turned out i had a bunch of issues and the common denominator ended up being the engine management ECU. I had light corrosion on two of the multipin plugs and the third was swimming in oil, which had wicked it’s way up from the cam sensor. A lot passes through the engine ECU including the CAN line from the seat sensor. Later models had a CAN gateway module but mine doesn’t. but if you get a break in the CAN bus then all sorts of strange things start to happen. All sorted now.
