Upgraded HU. Car doesn’t read OABR

I upgraded my HU from entry level to a newer 4.1 hw level HU and the OABR doesn’t connect or recognized to the car.

The HU itself came from a newer M240i and came with CarPlay. However, I can’t edit any features by bimmer code and also my programmer can’t connect to setup full screen CarPlay.

I bought a second OABR Quadra lock cable with no luck. Any suggestions?

You need to move ethernet from Quadlock to OABR.
There are 4 pins.

Quadlock to OABR

What model year is your M235i? We do have wiring kits with the RJ45 to OABR cable included so that you don't need to repin quad lock.

PM if you need more details.
