Why didn't you install the 7874 in the WS6? I figure any time it isn't snowing you'll have that thing out so why bother putting it in the mystique. You can pull that Monsoon POS out of the Pontiac and put it in the Mystque, then concentrate on making a good system in the Pontiac based around your new HU.
Unless you... like... the Monsoon's "sound quality"
