Happy to join what appears to be a fine group...
I run a 2009 ZR1 aka Big Bird with a V1 and LI...currently parked for winter and a 2013 ML63 AMG aka Frank that had a Blinder hp-905 / 9500ix and this past weekend I added AL Priority and BEL STiR+ (yes added)...so currently 4 heads front and one (AL) rear.
The intent is to remove the Blinder and 9500ix in due time with the 9500ix going into my new 2013 Lexus RX350 aka Lexy.
I also have the bt AL module.

I'll post some pics when the forum permits..

Cheers
