Alfa Romeo Giulietta aftermarket head-unit install issues (harness faulty?)

[Choogz]

Hi All,

Just had a head-unit installed at autobarn over the weekend to give me apple carplay and reverse camera features and just wondering if anyone has done a head-unit install themself?

Currently experiencing issues with the steering wheel harness (all have been bought from the aerpro website as per requirements) but don't know if the infoadapter harness is causing issues for the reverse camera and head unit (static white noise)

Should I just pull out the infoadapter and do without it because it seems like a part connect2 haven't updated for 10 years and my Giulietta is a 2015 model.
