Love the unit. Dual band radio(V/V, V/U, U/U)with volume/squelch controls for each side of the radio. It also does crossband repeat. Easy to read display, and you can select a green or amber backlight. Aprs function easy to use. I purchased a GPS unit from Greenlightlabs that mounts to the back of the head unit and draws its power from the head unit itself. The menu is rather easy to use and follow, but if you need the manual you will need to print it yourself as it is on CD.
