Rear view camera retrofit

[JayGee]

Hi

Locally (South Africa) the RVC is not offered on the new Yaris.

My car has the touch screen audio system - no nav yet though - and as far as I can tell, it should have an input for a RVC.

Has anyone retrofitted one with the OEM touch screen audio system yet?
Is it pre-wired? There seems to be an insert in the hatch (number plate light housing) where I assume a camera can be mounted. Does the radio have to be programmed by the dealer before it will work?
Any idea what other Toyota product's (locally the Fortuner, Land Cruiser range and Hilux do have RVCs) camera or 3rd party camera will work?

I'm not sure about the results I get on eBay - most of them look like they are for the previous gen Yaris.

I'd be more than willing to post pictures or create a DIY sticky, if I can get it working.

Thanks.
