Garmin GPSMAP 1243xsv Combo GPS / Fishfinder GN+

It means the unit has built-in 1kW CHIRP plus Ultra HD SideVu and ClearVu scanning sonar all in one chartplotter. No external sonar module required. Add a compatible transducer and you have full sonar capability driven by the chartplotter directly. Non-xsv variants of the GPSMAP line have less built-in sonar capability and rely on external modules for some functions.

No. The unit ships with the chartplotter and the network and mounting accessories, but the transducer is sold separately because anglers spec different transducers for different hulls and fishing styles. Common pairings: GT54UHD-TM for Ultra HD SideVu and ClearVu transom mount, GT56UHD for the higher-power transom version, or a thru-hull 1kW transducer for offshore deep-water work. We can help spec the right transducer for your boat.

Garmin Navionics+ for US and Canada inland and coastal waters. The Navionics+ chart card is preinstalled in the unit and includes Auto Guidance+ technology for automatic route generation between waypoints. The unit also includes a 1-year subscription for daily chart updates. After the first year, renew the subscription for ongoing daily updates or just keep using the chart at the version you've got.

Yes. The GPSMAP 1243xsv supports the full Panoptix line including LiveScope. Add the GLS 10 sonar module and the LVS34 (LiveScope Plus) or LVS62 (LiveScope XR) transducer and you get real-time live sonar imagery of fish movement around the boat. LiveScope is the chartplotter feature that reshaped tournament bass fishing.

Three things. Faster processor for fluid multi-window split-screen operation. Edge-to-edge IPS display panel for cleaner look and better viewing angles than the older non-IPS units. Smaller unit footprint per screen size, which makes retrofit installs easier on dashes sized for the previous generation. The platform is overall a meaningful generational refresh, not a minor update.

Yes. Two Garmin Marine Network ports let you connect additional GPSMAP displays, GMR radar, GCV scanning sonar modules, and other Garmin marine network devices. Sonar, charts, waypoints, routes, radar, and AIS targets all share across the network. NMEA 2000 handles engine and vessel data on the broader backbone.

GMR radar (Garmin Marine Radar) line, both dome and open-array variants, drives natively over the Garmin Marine Network. GMR Fantom solid-state radomes are the modern pairing. Older GMR Xpress and similar HD digital radars also work with the appropriate cabling.

Yes. The HDMI output port mirrors the chartplotter to an external monitor or video distribution amplifier. Useful for adding a flybridge display, a salon TV showing chart for guests, or a recording / streaming setup for charter operations.
