Don't mind me asking but if you are going through all this trouble to upgrade everything, why not ditch the factory HU? The sad thing on these GM vehicles is the outputs from the factory deck are just as bad as what comes out of the Bose. In my Saturn Outlook I used the Cleansweep and although I was much happier than what it was before I still wasn't totally satisfied. Pulled that factory unit out and installed a Pioneer AVIC deck and never looked back. Heck, I liked it so much I pulled that deck and put it in my Denali. Could not believe how much better the BOSE system sounded with just a head unit swap.
New units are can bus controlled so a swap isn't really feasible. Obviously you can replace it all which may be my course of action, but the whole basis here was to see if there was a way of hacking into the signal to get out what is necessary.
Also pretty sure that a replacement headunit wouldn't provide any gains on the newer systems IF you managed to talk the bus to keep the controls comparable. I haven't yet measured the outputs for complete verification as my nav crapped so yanking it all may be my approach instead of trying to continue to search for ways to integrate with it. The last few systems I've measured have been every bit as reasonable as an aftermarket headunit, signal normally gets jacked further down stream.
