First time mercedes owner

[doctorgonz0]

Hi folks. First timer here and first time mercedes owner. Great car but with a couple of hair pulling problems lol. I've posted up my most pressing issue in the electronics section and hopefully I'll be able to tap into your knowledge and experience to get to the bottom of this. Thanks in advance
