I have read everything I could find about aux-in in the forum but didn't found the following question ever asked:

Does anybody know whether a CD30 MP3 from corsa/astra could be fitted to vectra?

I have 2008 vectra c with CD30 MP3. It's a delphi unit without aux-in support. At the same time I see the astras and corsas from the same year have aux-in support but their CD30 MP3 has a different button layout. Here's a link to a CD30 MP3 from an astra/corsa: http://cgi.ebay.com/Holden-AH-Astra-...item2a08ab557d

Thus I wander what would happen if I installed one of these in mplace of mine. Would the board computer, clock and other settings still work properly?
