Unhappy Wiring harness / interface for Audio 20 replacement in 2006 SLK 350

I am currently replacing my Audio 20 head unit with a Pioneer head unit (actually it's being done for me). I am trying to locate a wiring harness adapter which will let me complete the install without having to cut any wires.

We currently have the Axxess AX-ADXSUI-MB2 CAN interface harness and the AX-ADXSUI interface box, but they don't seem to be able to recognize the car and do the CAN-BUS translation.

We have called Axxess but have not gotten the issue resolved yet.

I'm in the US and I would like to find out what needs to be done to get the interface working or know what harness and adapters I need to buy to get this install done.

Any assistance would be greatly appreciated.

I purchased that same harness but have not tried it yet. I'm going to install a clarion unit in a 06 slk, let me know what you find out.
