I thought I'd chime in here about aftermarket stereo. I considered the Clarion but could not locate one to match the CF green dash illumination. Found the Kenwood KMR-D558BT. Has a variable color illumination. Variable color until you find the output color to your taste. Has Bluetooth, external mic, CD drive, USB and micro plug all on the face of this Marine unit. The silver is a perfect match. I use an iPhone, syncs no problem. Sound seems fine. Purchased through Crutchfield in which I highly suggest, they offer lifetime tech support. Worth the extra $50 that I could have saved purchasing through ABT Electronics. The tipping point for me was to find the green illumination to match the existing CF dash lights. Clarion? Not bad.
