OK, I caved

Turns out that I acutally didn't have the RCD330+ but I have the cheaper RCD360


Ive now purchased the RCD330+ Desay one with the USB rear port to route down near the ashtry to replace it. I didn't get DAB like I wanted but, this will work with a reversing cam that the same website sells that I can add at the later date for about £90ish and it looks OEM.
Honestly, only after market one that I would have bought is the Alpine one but they no longer exisit so RCD330+ it is.
