Had my last response open for awhile (went AFK for a bit) - just saw the links to prices post (tks, WarmandSCSI!). As I feared, the head unit itself is almost $3700.
I'll price this out later - that'll be a tough pill to swallow, LOL. The majority (with BigAudio) is right here - $$$-wise, best to go aftermarket. But the cubby hole is gonna bug me down the road...
