New head unit issues

[bouncer117]

Hi there wonder if anyone can help me. Just installed a new head unit and now have 2 issues.
1. No rear speakers. After looking around on here and in other places easy option is an adapter, but I'm unsure which I need pc9-401 or pc9-404?
2. No radio. Do I need a certain adapter to power the aerial?
Also what is this connector for? Do I need to worry about it?

The plug is the aerial so probably why you have no radio.

That went wrong. The aerial is allready plugged in I will take another picture of the whole back of the head unit.

Maybe try swapping what you think is the aerial for what I think is the aerial? Weird to have 2??

These are tied together.

If you have two there is a chance the better one is planted in you window screen. Little black box on the passenger side. It's common so try both to get radio working.

What do I connect it to though? It doesn't fit anywhere

It's about quarter of the size
