I install Alpine CDA-118M (in glove box) with the MC20 remote (drivers area) in my boat a few weeks before I took it into Exile. I haven't spent a full day on the water with it yet, but i have played around with it for several hours. The dual zone feature on it is great to have. Liked being able to turn my tower speakers off and still play the cabins while I was working on my hot water shower install. And like David said Alpine has excellent iPod functionality. It is much easier to use then the Kenwood deck I had previously.
