I accept your points on the limtations of the RNS-D, but its the first time anyone has come forward with the idea of downgrading to the pre facelift console that I'm aware of....

Your first problem is that the lovely vevona wood that you have wasn't around pre facelift, so you can't get a single din unit in the right wood. You would have to instead change the whole car to walnut, which is do-able, but a pain.

Your second problem is getting the climate to work. Its well documented what is needed to get a facelift climate module working in a pre facelift car, as they are physically very different shapes, but electronically similar. However, we've never contemplated whether a pre face climate module will 'just work' in a post facelift car. It may well do, as you have to add extra connections for the canbus post facelift, but none are moved or taken away I believe.

Then you have the reverse problem of other folks, because your current bcuttons on the console are all non latching, but the pre facelift ones are, you will need to do some hacking around to get the fog lights to work as they are directly wired into a control module that is located in the passenger footwell. Also the heated window, heated seats and hazards will all need rewiring, but at least the wires are physically near the console.

In my opinion, a professionally fabricated modification to the existing hole sounds like a bargain at a mere £100 - £150 as the alternitive will cost that in parts alone, before you start putting in a lot of effort....

Happy to give you some more pointers if you go down the retrofit prefacelift route but it'll not be easy!
