Avin Avant 4 Installation Guide (Video Link)

[X5only]

Seems to be some sort of software issue. I'm unable to code DSP per these instructions using IBUS-App: https://support.avinusa.com/hc/en-us...l-Update-Guide

INPA/DIS/Bimmercode can talk to the DSP, turn it on, etc. No error codes stored. When turning on DSP using these apps, the hissing sound goes away.

Is everyone else able to code their DSP using the IBUS-App? Are you able to read data off it using IBUS-App?

I tried a couple of times to read the factory DSP settings from within the app but I could never get the read function to work. I didn't press the issue since my DSP and Avin are working fine and I had the mid, not nav, to begin with. Thought it was odd though.

I have raised the issue with IBUS-App dev on their facebook page. They're asking what DSP version INPA shows. My X5 is at the body shop at the moment and unfortunately I didn't save that info. Do you or any one else have their DSP version info as shown by INPA?

NCSDummy and NCSExpert worked perfectly. I coded the DSP module value to "Controls: mid_basis" and verified it. Clearly, I-BUS App has a bug in coding the E53 DSP module. However, it is able to code LCM and PDC.

Hi Everyone,

Full disclosure, I'm an E39 M5 owner, but came across this thread as it's one of the few sources of knowledge info regarding the Avant 4 - so thanks for all those who contributed!

I'm posting because I've been stuck in my installation of the DDVR for almost 2 weeks. Regarding the 3-pronged wiring harness (that takes inputs from reverse camera and dashcam, then outputs to the head unit), Avin sent me an incompatible harness. I've been trying to get them to send a new harness, but instead they've taken two weeks to change the installation directions, which do not help as the connectors are not compatible with the reverse camera.

Does anyone know of the name of the wiring harness (circled in my attached picture). I'm looking to just buy a replacement from ebay/amazon/etc. but none of my searches are yielding any results. I appreciate any help you can provide - thanks!
