Hi Neil, I have connected my factory reverse camera (6Volts) to Sony http://www.sony.com.au/product/xav-701bt. Also I successfully connected steering wheel control (purchased in AutoPro) and installed new fascia (also from AutoPro) to match the double din slot. My car is Prodigy 2010 with factory Toyota reverse enabled unit. If you are still planning to install your unit I can try to help you. Cheers Adem
