Humminbird IDMK RM A16 In-Dash Mounting Kit f/APEX® 16 Product Description

Upgrade Your Helm with the Humminbird IDMK RM A16 In-Dash Mounting Kit

Installing a high-performance marine electronics unit like the APEX 16 requires more than just slapping it on a surface—it's about achieving a seamless, professional finish that withstands the rigors of boating life. The Humminbird IDMK RM A16 steps in as the ideal in-dash mounting kit, specifically crafted for those who prefer a rear-mounted bracket approach. This silver aluminum solution locks your APEX 16 control head firmly in place, delivering a sleek, factory-like appearance at the helm while protecting against vibrations from rough waters or speedy runs.

Boaters know that a stable mount isn't optional; it's essential for reliable sonar readings, precise charting, and intuitive control during critical moments on the water. Drawing from years of real-world marine installs, this kit excels in environments where space is tight and aesthetics matter, like center consoles or sportfishing setups.

Key Advantages for Serious Anglers and Boaters

  • Rock-Solid Security: The reinforced aluminum bracket paired with stainless steel hardware ensures your APEX 16 stays put, even under heavy throttle or choppy conditions. No more worrying about loose fittings distracting from your fishing focus.
  • Flush, Professional Fit: Designed for in-dash integration with rear mounting, it minimizes protrusions for a streamlined helm that looks custom-built and reduces snag risks for gear or crew.
  • Durability Built for Marine Abuse: High-grade aluminum resists corrosion from saltwater spray, while stainless components shrug off rust—perfect for offshore adventures or freshwater pursuits.
  • Easy on the Eyes: The silver finish complements most boat consoles, blending seamlessly without overpowering the design.

Unlike basic surface mounts that leave cables exposed and units vulnerable, this rear-mount kit hides the bracket behind the dash for superior protection and wiring management. It's a game-changer for upgrading older helms or retrofitting new APEX units without major surgery.

Perfect Fit for APEX 16 Owners

This mounting kit is tailored exclusively for all APEX 16 models, ensuring precise cutouts and alignment every time. Whether you're running the APEX 16 for its advanced MEGA Live Imaging, AutoChart Live mapping, or 10-bit Solix display clarity, the IDMK RM A16 maintains full functionality without interference.

Pro tip from seasoned installers: Pair it with Humminbird's cable routing templates for a hassle-free setup. The single-unit design keeps things simple—no extras cluttering your inventory.

What's Included and Quick Install Insights

Everything you need arrives in one package: the robust aluminum mounting bracket and corrosion-resistant stainless steel hardware. No hunting for mismatched screws or brackets.

  1. Measure your dash cutout to match APEX 16 specs (typically around 15.5" wide by 9" tall—double-check your model).
  2. Secure the rear bracket first, routing cables through grommets for protection.
  3. Slide the control head into place, tighten with provided hardware, and test for play-free hold.
  4. Seal edges with marine-grade silicone to block moisture ingress.

Most DIYers complete this in under an hour, but for complex dashes, a marine electrician ensures watertight perfection. Regular checks post-install keep it performing like new.

Long-Term Reliability Backed by Warranty

Humminbird stands behind this kit with solid coverage, giving you peace of mind for seasons of use. Focus on landing that trophy fish, not fretting over hardware failures.
