Black Max® Highway Advisory Radio



Black Max is the electronic unit of a Highway Advisory Radio (HAR) system. It supports multiple components, allowing you to add or upgrade your HAR station without replacing the entire system. Black Max was designed specifically for use with HARs, which provide motorists with up-to-the-minute travel and weather information from their standard car radio.

The sleek design of Black Max puts all the controls up front for easy access. The rack-mounted component system lets you build the unit to suit your needs, leaving room to accommodate future modules. Simply remove an old module and install a new one, or add the latest technology - all in just minutes.
