The MGR300B is a marine dashboard stereo that draws on Boss Marine's decades of experience in this field. The sound quality is what we have come to expect from Boss Marine, capable of delivering 60 watts (peak) across 4 channels, which is a remarkable feature for such a compact stereo. - The MGR300B can be used as a simple AM/FM radio, but most of the time we will use it for audio streaming, playing songs from our smartphone via Bluetooth connection. However, we can also connect external players via USB or the aux-in port with a 2.5 mm connector - The USB port and aux-in are located at the rear and can be moved to the console with the optional MUSB35 accessory - The display is large in relation to the small size of the front panel and is also suitable for viewing multimedia content. - The MGR300B has a rotary knob for volume control, which is particularly convenient and useful for immediate adjustment, unlike touch buttons, which certainly take longer to adjust.
