Haha no its all good...been called a lot worse myself. BTW...Success!! Put the steering wheel controls in just now and all works fine. Hardest part was getting that little blanking plate out with the fear of breaking the surround. Kudos to the authors of how to add steering wheel controls to your i30, agentr31 and i believe ibrokeit also.
Next up new aftermarket head unit and hopefully the controls continue to work with it...
So those were the audio controls then? BTW Thanks! I mostly only contributed advice on how they work and interfacing - which I hope is useful.
In regards to aftermarket head-units - yeah. It is a case of hoping it seems... there has been one, or two, reports of where it hasn't worked. But it can be hard to know, for certain, if it is because: the head-unit just can't support that setup; or isn't wired up correctly; or isn't programmed correctly; or some combination of them - often due to lack of detail in install docs (if any)... which makes it hard esp. for DIY/home install. Or if the head-unit is faulty in that regard. Such as (and I will note the first head-unit installed turned out to be faulty and was replaced by supplier)
Aftermarket Android double din where the steering controls still didn't work with it in the end (but wasn't being worried about by owner).
BTW - this might not apply to your year/model (it might be too early)... Some models/years (I don't know which - others will probably know) of the FD (first generation body type) diesel has cruise-control functionality built into the ECU, etc. - and can be activated (if not present) by adding some wires to the ECU and soldering in some LEDS to the instrument panel PCB and appropriate steering controls (all though I think someone made their own). Anyway someone else probably will know/recall the details better - I really am not sure it applies to diesels from all FD years. I believe one of the topics here is a basically a How-To guide to do it.
FYI for FD petrol owners reading this... the above doesn't apply (AFAIK) as the petrol FD has an accelerator cable requiring mechanical additions (not so the diesels).
