I'm keen to know this as well. Found these 2 units on Ebay, and I'm interested in buying either. One is in Sydney and it says that it works with the original steering controls. While the other says it is plug in and play. Both are $600. Also the sydney one says they can do the install, (auto electrician) as theres comes with reversing Camera. Not interested in the camera as I have reverse sensors, but the unit it's self looks pretty good.
First unit is the one located in Sydney
What do you guys think?
