The Evolution of Manitou Navigation: From Paper Charts to Precision GPS
Manitou has come a long way since the early days. Here’s how navigation has evolved:
1986 — Manitou founded. Navigation meant paper charts, a compass, and knowing the lake.
1990s — Basic handheld GPS units appear. Accuracy is rough, but better than guessing.
2000s — Fixed-mount chartplotters become affordable. Color screens change everything.
2010s — Simrad and Garmin become common on premium Manitou models . Touchscreens arrive.
2020–2023 — Digital helm displays become standard. GPS integrates with engine data, stereo, and lighting controls .
Today — Precision GPS with 20 cm accuracy enables smart mooring and joystick docking assistance .
Types of GPS Systems for Your Manitou
Not all GPS units do the same job. Here’s what you’re actually shopping for:

Installation: What You Need to Know
Installing a GPS on your Manitou ranges from “plug and play” to “call a pro.”
NMEA 2000 Networking
Most modern marine electronics use NMEA 2000—a standardized network that lets devices from different brands talk to each other. Your GPS can share data with your engine, stereo, autopilot, and VHF radio over a single cable backbone.
If your Manitou already has NMEA 2000: Installing a new GPS is as simple as connecting the display to the network backbone. The GPS will automatically see your engine data, fuel flow, and any other connected devices.
If your Manitou doesn’t have NMEA 2000: You’ll need to install a backbone kit (about $100-150) before adding devices.
Power and Mounting
Most GPS displays mount on the helm using a RAM mount or direct bracket. You’ll need:
- 12V power (tap into an existing helm circuit or run a new fused line)
- GPS antenna (often built into the display, sometimes external for better reception)
- Transducer cable (if adding sonar)
Pro tip—run the transducer cable away from other wiring to prevent electrical interference. And always leave a drip loop where cables enter the boat.
Calibration
For advanced systems like the Minn Kota heading sensor used with trolling motors, you’ll need to calibrate by driving the boat in two complete circles. The One-Boat Network app guides you through this process step by step .
