Hi everybody! This is my first post here so let me salute all of you. Now to business: I own an Audi S4(B5) from 2000 and would like to retrofit an RNS-E replacing my Concert I. I've been researching everywhere but couldn't find any definitive pictures that would clarify my doubts. I know I must replace my single din console with a double din but then the picture is far from clear. For instance, concerning the climatronic unit, I believe the part number I need is '8D0820043M B98' but I'm not sure. If it is, then according to the info on VAGCAT.COM it would cost a whooping 514EUR! Since I can't afford to spend that much, and I can't find a suitable unit on eBay, I'm studying how to customize my own to fit. I couldn't find any pictures anywhere so I choose to take one of my console and draw an imaginary line in red with the same size and shape I imagine the double din HU has. See below: Is this line correct? What puzzles me is that I would have to trim the part around the HU and not the HU itself to give it the same shape as the proper unit as bellow: But since this piece is not connected to the main module how can I mount both on the new console afterwards? Can anyone explain how this is done?
