Self-Contained GPS Speedometer & Digital Odometer
Upgrading the dash on your vintage Honda Odyssey (FL250 / FL350R) or Pilot (FL400R) usually means dealing with missing speedometer gear drives or broken mechanical cables. This 3-3/8" Waterproof GPS Speedometer solves that problem completely by using an ultra-accurate GPS satellite signal receiver to measure true ground speed regardless of tire diameter, gearing ratios, or drivetrain modifications.
Built with 100% waterproof and anti-fogging construction, this gauge is designed to survive heavy dust, rain, mud, and pressure washing out on the trail or in the dunes. A high-contrast red LED backlight provides crisp night visibility.
Multi-Function Tracking & Unit Selection
In addition to traditional analog needle speed tracking, the integrated digital display provides essential trip data at the push of a button:
- Current Speed & Selectable Units: Press the rear button to easily toggle readout between MPH, KM/H, or KNOTS.
- Trip Meter: Tracks distance for your current ride (resets to 0 when key power is turned off).
- Total Odometer (ODO): Cumulative lifetime mileage tracker (stored permanently in memory).
- Course Over Ground (COG): Digital compass heading readout.
Installation & Satellite Signal Notes:
- Dash Cutout Dimensions: Requires a 3-3/8" (85mm) mounting hole with at least 2-3/4" (70mm) clearance depth behind the panel.
- Fast 3-Wire Wiring: Simple 12V/24V setup requiring only Power (+), Ground (-), and Lighting (+) connections.
- GPS Receiver Placement: The included compact GPS antenna can be mounted above or concealed underneath plastic hood panels and fiberglass bodywork with a clear line-of-sight to the sky.
- Signal Acquisition Time: Initial satellite lock takes roughly 30 seconds upon first cold power-up, acquiring signal in under 3 seconds on subsequent restarts.
