Hi all!

I'm retrofitting my prefacelift car from an Audo 20 to Comand so I ordered a unit from a scapyard. The Comand unit I ordered has the part number A2129007225 and it's from a 2013 facelift car (swedish).

I see that pre-facelift NTG 4.5 cars do have the 2 button style controller, but this post-facelift car shows in the EPC that the Comand was used with a 4-button controller.

Here comes the questions:

1. Do I have a 4.5 or 4.7 Comand? - I do have the 4.5, EPC show DVD-ROM navdisks for a 4.5.
2l Is the 4-button controller really necessary or can I use the old one?
3. The fan ducting. Pre-facelift cars seem to have a lot of air ducting, but post-facelift cars appear to have a bit simpler air ducting with a different fan than pre-facelift. I have a pre-facelift car - which air ducting should I buy? Are both ducting styles sufficient and do both ones fit?
