Anyone know if this is plug and play going from only audio to audio +phone buttons connected to the PAC swi-rc-1 steering wheel interface? first image is my 2001 xc70 with a plug missing, is this for the phone or another accessory? ive seen on the wiring diagram theres another audio button..

That was an unrelated post, more about switching to a two wire clock spring to accommodate a three spoke wood wheel. Neither had accommodation for a phone as I recall.

I found the phone buttons, they are hidden. And they are connected on the board to the main connector, so should work but doesnt. have to do some more research...Funny Volvo hid the buttons, i assume only cars fitted with the telephone got the phone button, no bluetooth in 2001??

**i dont have a PAC swi i have a Crux and unlike the PAC the Crux is not programmable
