Just wanted to know if there was a definitive list of the different versions of the RCD510 head unit at all?
I've seen many various types with different button configurations, dependent on locations, i.e. if it's from the USA, from Germany, the UK or China for example.
At last count it was about 5 or 6 different button configurations.
I have recently purchased this one: RCD510: PN: 5ND 035 195
I've seen these also: RCD 510:
