DNX690HD, excellent sound very pleased with it so far. You have to play around with the equalizer and get the bass settings right, I thought they lost the sub on the Bose system. The Bose speakers are fine unless you want to drop another couple G's I don't think it's worth upgrading them.
Unfortunately I looked on Ebay and I don't see the stock head units moving. Ohhh well, maybe I'll put mine up for a cnote aand see what happens. And honestly if something happens to this unit after the 2 year warranty I'm not going back to the stock one. I'd just pop in a new HU, so no need to keep this hunk of garbage.
