I installed mine this weekend and it works, but there is one slight issue. When I have my sirius plug'n'play receiver on the cradle, the cd volume is about 8-10 steps lower than normal, even with the sirius turned off. If I remove the sirius tuner from the cradle or unplug the aux cable, the volume returns to normal. The sirius volume is also the same 8-10 steps lower than the radio any time I'm using it. Is this a problem with the board or just the nature of the beast? For comparison's sake, in my last Subaru (1990 Legacy) and my Dodge truck, both with the same JVC HU; I had the keep the line in volume for the sirius about 3-4 steps higher on a 0-60 scale.
