I may be mistaken, but if you used the VW harness, the memory and Ignition are swapped for VW. Swap those and that should cure. I would check it first.

You are right here... the VW harness although it is the same plugs... wires do not match up... connect your yellow(constant) from the VW harness to the Red of the alpine harness and the red(ignition) from the VW to the Yellow of the Alpine harness<-- Easy fix... or if you want wire colors to match for possible troubleshooting down the road use pull the yellow and red wires out of the VW harness swap them and plug them back in!!!

Is this only true for Alpine units?
I'm about to install a Kenwood unit, do I need to swap the red and yellow in this too?

cheers!

I'm about to answer my own question.... yes, its true to all head units...not limited to Alpines only.
Well, I changed my mind about the kenwood unit and installed an Alpine Unit.
Much better sound than the factory radio...the only replacement is just he HU.
