I bought the unit as a replacement for an older Alpine that had quit before I bought my boat.
Installation was easy and the unit performs as expected. Good radio reception, nice clear local source sound too. I bought this one for a couple of reasons. One it is marine rated so it should stand up to the dampness encountered in a boat. It has the multi input music player tray that handles my daughters' Ipod and Zune players. It also has a very easy to use wireless remote which is my main way to operate it. I have run it all summer, the boat has probably been out on 25 or 30 days. Never a hiccup.
