Yes, I have searched and apparently only a few have this combo but no one has given or suggested how to go about the wiring. The problem is that PAC say the SWI-ALP is only suitable for the 2006 Z. I have tried wiring the SWI-ALP with my Alpine HU but have only succeded partially: only a few functions are working (volume up and volume down but in the wrong place-other functions will not be programmed at all).

I think I have read somewhere that the wiring WILL work on a 05 as long as the Infinity G35 instructions are followed. Is this true? Also, anyone succeded in "mating" the SWI-ALP with an IVA-W200 on an 05 Z with stock steering wheel controls? I mean the controls suppied with the stock HU on the LHS of the steering wheel (which we get as standard on EU models BTW). Any help would be greatly appreciated...thanks

 

No Z's came with steering wheel controls until 06 at least in the US...

 

I have an 03 model EU Zed with stock steering wheel controls, an d have wired a PAC SWI-ALP into my W200Ri. I have volume up/down, next and previous track, mute and mode shift all working.
