Clarion also makes a din sized center channel... Good stuff...

I think I'm going to order the Pioneer Avic-Z3 in the next day or so... But I'm probably going to loose vents in the process... we'll have to see what I decide once I tear into it.

Then which ever din goes unused I'm going to put a ScanGauge II, Looks like it'll end up being a priceless accessory.
