Head unit for Carplay for Gen 3

I've just bought a 2009 3rd Gen Prius which has a cd player and not headset.

I'm based in uk and interested in installing a head set with CarPlay. Could any advise on what maybe suitable that I could install myself?

I have seen that there are lot's of similar posts but nothing from UK, and any advise on compatibility of installing it in a Prius that only has a CD would be appreciated too?

Also, whether the reverse camera would work with the function of the car.

Thanks so much,
David
