Adventure Radio Kit – GMR25 Waterproof GMRS Mobile Radio Kit and External Speaker

Description

Overview

Reliable communication is the backbone of any safe and successful group trail ride, and equipping your machine with the high-performance GMR25 waterproof GMRS mobile radio kit ensures you never lose touch when exploring the backcountry. What this product is: a compact yet powerful 25-watt mobile two-way radio system bundled with a high-output waterproof external speaker, engineered specifically for open-cab off-road vehicles.

Signs This Part Needs Replacement

While ruggedly constructed for extreme trail environments, communication hardware can occasionally experience issues from electrical surges or physical damage. You should inspect or replace your radio setup if you encounter a completely dead display screen caused by an internal power short, severely distorted or non-existent audio output from blown internal components, broken antenna mounts resulting in zero transmission range, or persistent water intrusion behind a damaged chassis seal.

Frequently Asked Questions

Do I need a license to use this GMRS radio?

Yes, operating on GMRS channels requires a license from the Federal Communications Commission (FCC) in the United States, though the application process does not require a test.

What is the communication range of the GMR25?

Under optimal conditions across open terrain, the 25-watt radio delivers a 10 to 12-mile range, though heavily wooded hills and mountains can alter line-of-sight distance.

Is this radio kit fully waterproof?

Yes, the GMR25 features an IP67 waterproof and dust-resistant chassis rating when data ports are properly closed, protecting it against heavy rain and mud splashes.

Can I connect headsets to this radio?

Yes, the built-in Rugged Ready 5-pin port allows you to easily plug in compatible intercoms, headsets, or multi-radio expansion accessories.

Will this radio work with other brands like Midland or Motorola?

Yes, it is fully compatible with all standard GMRS radios from manufacturers like Midland, Motorola, and Uniden, as well as FRS radios on shared channels.

Where should I mount the external speaker?

Mount the waterproof external speaker near the driver or passenger head area on the roll cage so that incoming audio cuts cleanly through ambient engine noise.

How should I wire the radio to my vehicle?

Connect the red positive lead and black negative lead directly to your 12V vehicle battery, ensuring the inline fuse holder remains intact for circuit protection.

Can this radio hook up to a 24V system?

No, the GMR25 is strictly designed for nominal 12V automotive and UTV electrical systems. Connecting it to a 24V source will cause permanent damage.
