STX head unit into my SL

[lukastonks]

Hey

I’ve just picked up an STX head unit to chuck into my 2016 SL. I know I need an antenna plug which I’ve sorted but I’m trying to get reverse camera, steering wheel controls and head unit lights to work. There’s two plugs from my SL harness with only one plug available on the new head unit. Wrong size.

Some help please

This is the part I hate about stereo systems. I don't have steering wheel controls in mine and mine's much older so I can't help except to bump this up and hope someone else can chime in.
