Well, Garmin finally announced the new Marine lineup for next spring. More confusing numbers and letters, a new line of 4" units and TWO separate 5" units, as well as new radar and new large-screen systems. All of the compact units (4" and 5" diagonal screens) come with internal gps receivers, so if you need the external receiver, you'll have to buy it separately. This is probably a good thing, as it cuts the number configurations to sort through in half. But if you're in anything but an open console, you'll NEED the external antenna; Garmin's betting strongly that people realize this, or that all the retailers make a note of it.
The introduction of the GPSMAPs 4212/4012 and 4208/4008 signify a new era for Garmin. With 12.1" and 8.4" size screens, their new network chartplotters are making a direct run at Raymarine's E120 and E80 lines. Garmin's system will be a bit cheaper; how it stacks up competitively will be determined when people can finally get their hands on them
The biggest change in the Garmin marine system is the introduction of BlueChart g2 Vision. Not content with BlueChart g2, with it's 3D views and port photos, the new Vision-compatible units feature a worldwide satellite cartography basemap, and Vision adds a more sophisticated 3D view with perspective choices, more port services and coastal roads, more, and higher-detailed port photos and marine charts, and something new called "auto guidance technology," which essentially plots an auto-route path in the water. This will be revolutionary: as the smartest innovation in chartplotters, or the most destructive, dangerous idea Garmin's ever had.
