Hi all. I'm working on installing a Boss Audio BCPA9 headunit on my 2001 Corvette. I got it all hooked up, and everything is working great until turn it off, then all the memory gets wiped. I've confirmed that it's getting 12V constant power on the yellow all the way up to the HU harness. Ground connection tests good, and red ACC power is functioning as it should. This is the only thing standing in my way from buttoning this up and getting on with my life. Anyone have an idea?
