Right, having seen many posts on the topic and having been frustrated myself, I have finally managed to get the speed-sensitive volume function of the audio unit to work, with AFTERMARKET units supporting this feature.
It really is remarkably easy as well!
It turns out that up until MY 01, the function was controlled not by CAN bus, but by Speedo output 2 from the dash readout.
This is still present on my (MY 05) A2, so I presume it'll be there on most others too.
Basically, all you need to do is link up this output (pin 31 on the blue 32-pin connector behind the dash pod) to the input on your head unit (usually pin 1 on the power block).
I did this this afternoon and am pleased to report that it is working well.
As my .sig says, my head unit is a Blaupunkt Woodstock DAB 54.
For any more details, please drop me a line.[25][23]
WAS : A2 TDI SE 2001 Ebony Black Pearl (The Little Tank!)
NOW : A2 TDi 90 Sport, OpenSky, winter pack, ISOfix, all-round fogs, climate control, all-round electric windows, Blaupunkt DAB54, genuine HID xenons and red leather! Not to mention CCC Tech chipping (118bhp), all round tinting and retro-fitted cruise control.(The NEW Tank). Black headlining and retro-fit Bose coming soon!!!
