Retevis MB4 CB radio kit brings AM/FM mobile contact with two-way NRC noise cancelling for engine and road noise. The high-contrast color LCD uses oversized text for quick channel checks day or night.
Mount it in a DIN-size slot with the gray rack or anywhere with the black bracket, a setup suited to off-road and trucking vibration. It runs on 12V and 24V systems through the cigarette-lighter connection, with VOX hands-free, CTCSS privacy tones, keypad lock and oversized knobs for gloved adjustment.
