I fitted my ancient Grundig WKC-5300RDS and DAB box into my A3 (2005 Sport 1.6FSI). Then I decided to put in Parrot Bluetooth. It all works fine - the speed pulse output works with the Grundig version of GALA to alter volume in response to speed. However there are a couple of oddities - the Ign output from the Connects2 is just that, not the ACC you get when you've switched off but the key is still in. A search on here suggested the only way to do that is to tap into a tiny red wire somewhere under the steering col shroud and then run a relay from that - anyone any experience of that? The other thing is the illumination - that is really odd - it lights up as soon as I put the key in (even if radio is off) rather than being connected to the lights - fair enough, but then it stays on after IGn off for about 90 secs. It also doesn't dim with the rest of the panel. The thing I don't get is - I don't think there is any other piece of equipment on the car that illuminates this way - but I can't recall what the audi stereo did. I have half a mind to just tap into the heater illumination - but I guess if that's all can bus operated, it may not help - anyone got any startling insight to this one? I'm not moaning about the connects2 it does what is says it will - I just hadn't thought it through properly.
