Yep. I am tracking. You need both of those. Shouldnt have said both harnesses as the first link is the maestro unit itself with a generic harness. 2nd link is the nnbs specific harness that retains all major functions.
For some reason i thought i had read that the vehicle functions wouldnt work with our Tahoes. I am stoked now that i found this thread. Cant wait to get my 8200 installed.
Did you ever get the 8200 installed?
I ran across this thread while doing some searching to see if the AVIC-8200NEX would fit in my 2010 Yukon XL. Crutchfield claimed that it would not - but then I found this thread and a few others where people had done it.
I just have to pick up a few more pieces (the iDataLink Maestro, the GM5 cable, the Scosche faceplate - am I missing anything) - and then maybe I can get the unit installed next weekend.
Crutchfield has an install kit - but it doesn't look like it comes with the Maestro and it has the Metra faceplate kit.
I'm thinking I might be better piecing out the extra install pieces rather than going with the Crutchfield kit.
