156 Audio Upgrade Options
Well, after a week of driving my new 156 (well, new to me), I've been reminded of how much I dislike standard single-slot CD players these days - especially when I used to have a Sony MP3-CD player in my old 156.
So, I'd like to replace the stereo in the new 156 with one that's MP3-CD compatible and can take an AUX input without having to buy expensive boxes of tricks to plug in to the back. The problem is, I don't want to lose the steering wheel controls when I do so - hence my question: Do the steering wheel controls work directly with a replacement e.g. Blaupunkt head unit, or is an additional wiring harness/loom adaptor required?
Ideally I'd prefer to be able to just slide my old Sony head unit in place (I retreived it from my old 156 before I sold it), but if I do that I'll lose the steering wheel controls, plus the AUX-In adaptor is about £35-40.
