So I have a headunit Im looking to install, and Ive been reading up on here, and just wanted to make sure I was getting the correct wiring harnesses and such. I have the bose system, and the navigation. It seems like theres no easy way to keep the voice portion of the nav, but everything else should work fine.

So I would need the harness such as this one:

And that will let me keep the bose speakers/amp and send it the correct signal I believe.

And then to keep the steering wheel controls, it looks like I would need something like this:

And I should be all set with just those two wiring harnesses I think....

Thanks for any input
