I ditched the pac and went with the maestro. The pac was always buggy for me.

That may be in my future i think. However doesn't it only with for certain head units?

They have a guide on their website. You can also change things up if you plug it into a Pc. I have a pioneer HU

Ok I'm just afraid I'll blow money on it and have it not work with this Chinese radio . I love this radio .just want it to work with my Yukon lol

What's weird is that SWC worked fine in my old interface and now with the PAC OS-5 it doesn't. The OS5 has a SWC indicator light on it that blinks when the buttons are pressed and this only works for me when OnStar is activated.

I was able to play around with the brown mute wire coming off the OS5 interface and found out that if I ground it then the SWC light on the OS5 interface blinks like it should. (The brown wire is looped originally in the harness) However this makes the head unit shut off as it thinks OnStar is on. I'm thinking I might bypass the red acc wire to the headunit from somewhere else not through the interface and give this a try.

Otherwise it has to do with the brown mute wire and the blue OnStar volume wire

The only wire not hooked up with my setup is a solid blue onstar volume wire, I have no where to hook it up. Manuals from PAC don't really explain this wire much so it may have something to do with it ...

The SWC works as it should during OnStar (when OnStar is activated the volume up and down control the onstar volume)

Thanks for your help guys lemme know if u have any tips. PAC takes forever to reply to emails and I don't have a normal schedule to call haha

Friggin PAC... :/

Well after talking to PAC they have no idea and suggested trying a replacement os5 interface or trying the rp5-gm31

So will be trying both of those

Can't use maestro with my Chinese unit I don't think

Will post updates

 

[Sidious999]

Well everyone it's done and working fine

Went with RP5-GM31 interface

Not sure why the PAC OS-5 from the FAQ here didn't work for me lol oh well

No static, SWC worked perfect without programming

Thanks for help guys!
