Can I add a front view camera to a 2016? does the head unit have an extra RCA jack for an additional camera? if not do I need an interface and does anyone know the part numbers needed to complete the process?

 

Simply, no you can't.

 

Coastal Tech has devices that will work in the Mazda3 and 6, but not the CX5. You could contact them and see if they have any plans on expanding the capabilities of the device. I have one in my Jeep Grand Cherokee and it works well.

Well, that sucks!
