Hi folks
I've bought myself a 2018 x3, it has the s676a amp. I was hoping to upgrade to the harman/becker amp since i have one collecting dust in my garage. I'm just wondering if anyone knows where the MOST BUS distributuion block is located on these vehicles. I bought a conversion harness from aliexpress. I'll try and link it here. I know its not going to be perfect. I had the same system in my e93 and it sounded good enough for me. Your help would be greatly appreciated. Thanks Dom

This is what ISTA show regarding the MOST bus connections in relation to the Top HiFi audio system.

Further ISTA HU MOST info. Looks like the orange optical MOST25 cable in your Ali kit plugs into A42*2B on the HU and the other end in the Top HiFi unit.

Thank you so much avi
That is very helpful. I'm surprised that the IC or HUD is not listed. Oh well thanks any ways. Dom
