  • Scan for AM/FM bands:
  • Store presets: Use the VHF radio’s channel up/down keys to tune, then hold a number key (1-9) to save a station.

    • The UI7 requires a clean, dedicated 12V DC supply. Do not share a ground wire with a windlass or bilge pump.

    Fuse: Install a 1A or 2A inline fuse (as per Icom specs) within 6 inches of the power source.

    The UI-7 is a slick replacement speaker grille and mounting dock. It replaces the factory AM/FM radio speaker grille on your dashboard (common in Toyota Tacomas, Tundras, 4Runners, and many GM trucks). It serves two purposes:
