Plugs into power socket, audio plugs into unit. Using 3m mounting tape on the base of the unit, unit mounted in glove box. Using 3m, antenna mounts in corner. Antenna works under the closed lid. I used the 3M product, which makes for a secure mount, so that unit could be removed easily in case I wanted to use the box for something else at a later date, being as the bike is only a week old. Works great!
