Garmin Catalyst to IMSA

Hear your Garmin Catalyst coaching through your helmet, not a tiny speaker under track noise.

This 6-foot adapter cable connects a Garmin Catalyst driving performance optimizer directly to an IMSA-wired helmet, so session audio plays through your helmet speakers where you can actually hear it.

• Direct plug-in: 3.5 mm jack into the Catalyst, IMSA connector to your helmet
• 6 feet of length for clean cockpit routing
• No modification to your helmet or device

Works with: Garmin Catalyst and any IMSA-style wired helmet.

Specs: 6 ft · 3.5 mm male jack · IMSA-style female connector.
