AUDIO Install

[21sH2]

So I just bought my H2 and want to install the new AVIC-D3 with BTB-200 bluetooth. Can someone confirm that these are ALL the adaptors/harnesses I need to retain and completely install all Bose/Onstar/Chime features??

Peripheral PESWIX (steering wheel)
PAC OS-2 Bose (bose, onstar)
CM1 Adaptor (Chimes)
Metra Mount CHE-304-01BL (Install Mounts???)

If you used a different part, what did you use instead?

Thanks in advance
