Hi everyone my first post here after joining 

I have a 2016 i30 with the GD-03 CarPlay unit and I wish to upgrade it to Kenwood double din (Mainly for better sound quality).

So far I’ve researched most of the stuff I need from this site 

There just a few wiring questions I have in regards to the rear view camera I would like to stick with the oem one.

According to diagrams I’ve found,

A9 is reverse - this is the signal from the gearbox to the headunit
A5 B/V ground - is this for the pop out mechanism?
A6 B/V power -   does this need 12v?
A14 B/V video ground - is this for the camera?
A15 B/V video - does this need 12v or 6v?

Also we’re do the rear reverse sensors play there sounds through? Is that a separate speaker? Meaning I don’t need to worry about it. 

Thanks for your help.
