Not having Bluetooth connectivity on my 2007 Z71 with Bose Head Unit has always been an annoyance for me. I was using an adapter that fed the sound through the Aux input but was never happy. I found this unit on amazon https://www.amazon.com/gp/product/B00XQCRZWU/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1. PAC ISGM751 Carconnect Full Integration BT with HF Calling for Select GM
I installed it last weekend and it truly is plug and play. The hardest part was removing the trim around the head unit without breaking it. The supplied harness is long enough that I was able to mount the adapter behind my glove box. Now I have integrated bluetooth for calls and streaming from my smart phone and can control from my steering wheel as well as the head unit. I did end up with the Blank Clock issue but thanks to Dan Creason on Youtube I was able to fix the problem. If you would like to add integrated bluetooth capability to your existing head unit I can definitely recommend this system.
