    AVANT 3 Help before I smash it

    Well after waiting several weeks and 4 installed days I finally got the I-Bus app unlocked. But no sound in any application. Please note that my system was in full working order prior to this incredibly frustrating experience.

    Virtually non existent model specific installation instructions and unless I am missing something not sure how an X5 and E39 non dsp install video is of any help at all.

    Perhaps something like this would have been just as much help:

    take the head unit thingy out of the box then connect the long cable thingy to the back of the car then turn it on and confirm that you have no sound output at all so check all your thingys are plugged into other thingys reassemble your car and get installer to drive 60kms home again DONE

    Unless you are a seasoned BMW tinkerer and electronics guy then a bunch of assumptions is all that is required apparently to install it. After looking at all the available connections and removing the amp, stacker, nav etc we eventually found the box hidden behind a panel against the inside of rear quarter panel and one could only assume that this is all that is required but perhaps I and my installer are just complete idiots. Can someone PLEASE suggest some troubleshooting tips

    I reconnected my video unit and had everything working, along with the dsp amp, this then left just the radio unit removed and replaced to the wiring harness, suggest if that doesn’t work I asked two questions to their web based support area and had very quick, 15 min responses. Hope this helps

    I kept getting generic do this do that and it took days to get the IBus unlocked then when it did unlock still no sound. Needless to say I was pretty blunt about their lack of instructions.
    Apparently there can be a gremlin in the software but everything works on the display and even shows the songs playing but the coding part of the app says no communication with the module for dsp...
    The time difference doesn't help either.

    Yes running Ibus 2.0 but when I go into coding for DSP it says no communication with module. Did you only run the 6m cable to the back and connect into the plug that was attached the box in the boot?
    They have told me that is only thing required....anyway will wait and see

    Yip ran to the boot, nothing else connected, USB main port into the USB connector for the Ibus. Except aerial and rear camera.

    Subscribed. Any update on getting this working? I'm going through the same thing with my E39 540it with Nav and DSP. The connector they sent doesn't have the speaker wires lining up to the BMW side of the harness. I'm thinking I'll need to splice in a new connector to get the speaker wires lined up. Not sure what else to do.

    Im currently installing an Avant 3 into my 1998 740 with DSP and its been rough going. I added the backup camera and that was a pain to get installed properly. What is this about running a wire into the trunk, is there something I am missing. Also, for some reason I can only get audio from the front speakers and nothing from the rear. This wasn't an issue with my stock system.

    You have my condolences getting stuck with their pile of shit. If you have NAV/DSP you need to have the 6m extension cable as it is controlled from the units in the trunk but as you might be discovering that is no guarantee of everything working. AVIN USA should actually call their system a true PLUG AND PRAY. Unfortunately my front speakers have now disintegrated but I know that the Bavsound kits do work well but unsure about what do with getting another head unit.
    Best of luck trying to sort it all out as it seems that everyone experiences different probems

    Thanks for the response. What does the 6m wire look like and where exactly would it connect to? The lack of any sort of instructions or guidance is ridiculous considering the cost of the unit.

    I see, my car doesn't have nav so it makes sense that I wouldn't need it. I did reach out to them saying that I didnt receive screws to attach the screen unit to the bezel and was told they arent included. Seems tacky to me that I would spend $1000 on a nav unit for them to cheap out and not provide screws.
