Thread: System upgrade. What am I missing?

So far I have installed Sony HU with the simple harness adapter, front 5.25" kickers, rear 6x9" kicker (have 4" on order). My gtp came with bose and OS my door chimes work and I got sound because i tapped into the pink wire. Now I have rethough the process and I want my OS and steering controls to work. So the question is will the adapter GMOS -04 will let my OS work and the SWI-PS work for steering controlers? I have COCD and those things not working is annoing me lol.

And to answer your question, yes GMOS-04 and SWI-PS both will fix your issue.

The pink wire is the power wire for the Bose amp. As far as the chime I just hooked up the wires just like it said in the instruction.

i was trying to put mine in yesterday and did know where to plug my red wire into what did you splice into ?? i also coultn get my sound to work for some reason but the radio would turn on when i would touch the red wire to my cigarett lighter

Is it the same for an 05?

I'm guessing I need the adapter for an 04+ GP so I can plug into the GMOS-04?

Ok I forgot an important pice of the puzzle. I have a 03 GTP so I guess Ill just have to deal with my OS not working.

So no one has their on star working with an aftermarket radio on a 03 with Bose?
