Pyle PLMR17BTS AM/FM-MPX In-Dash Marine Detachable Face Radio with SD/MMC/USB Player and Bluetooth Wireless Technology
Radio was easy to install, instructions were clear, and the unit works very well.  I enjoy having the BT hookup to my iPhone to allow playing music when we get in part of the Chesepeake Bay where standard FM signal is poor.  Sound quality is much better than the OEM radio supplied with the boat.  Since I boat in rain as well as sun I installed a flip up cover for the radio face since my mounting spot is not under cover.  Great Radio for the Price.
