Additional Information
With a full arsenal of tools and new features, the Helix G2N CHIRP Fishfinder Chartplotters are now networkable with other Humminbird units and Minn Kota trolling motors, including Humminbird CHIRP Radar, Auto Pilot, 360 Imaging, and i-Pilot allowing users to "follow the contour." These units also feature Bluetooth capability, so you can view messages and missed calls from your head unit. All Helix G2N models now come with CHIRP technology for impressive detail and accuracy in virtually any application. A new user-friendly interface allows you to navigate the system quickly. AutoChart Live lets you map structure and contours on your screen and save them onto your micro SD card. The new SmartStrike feature gives you your own cheat sheet to the best spots on the lake. Mark up to 2750 waypoints and 45 routes, then share them with friends with full network capabilities. The widescreen format allows side-by-side displays of sonar, DI, SI, or GPS screens. Sonar options include Down Imaging (DI), with extra clarity and details down to 350', and Side Imaging (SI) that gives users up to 480' of side-to-side views of logs, weeds, and fish. The internal precision GPS comes with built-in basemap. SD card slot accommodates Navionics and Lakemaster map upgrades. 500 watts RMS.

What extra features are included with the G2N Vs. the G2Combo? Is it blue tooth only for an extra $100.00 or is there something more to be gained??

Asked by: Reelameal
The difference between the Helix 7 CHIRP SI GPS G2N and the HELIX 7 CHIRP SI GPS G2 is basically the same other than with the G2N model you are able to Networked with another 7 G2N, Helix 9, 10 or 12 and the unit would be compatible with I Pilot Link. The G2 model cannot network and not compatible with I Pilot Link.
