Sony DSX-M55BT Marine Radio, Mounting Kit, and Pac Adapter
Has Bluetooth, and USB. With kit it fits 98-13 SG/RG. Will be able to retain use of handlebar controls. 5-band equalizer with 8 presets. Makes it easy to get the sound you're looking for. This radio is a lot for the money. Also good enough to build a great sounding system around.
