|lievre||I find that on the paper the garmins look good but then you always have to pay for more accesoies charts XM weather and in the end it doesn't really works. Why do we pay for charts that NOAA publish for free same for weather data.|

The same goes for adding devices. While the ethernet connection is deceptively simple in appearance, there is far more going on under the hood. Essentially your devices must act as network bridges to move traffic around.
I am sure that both the sales methods of manufacturers and the "packaging" they use make NMEA2000 appear "easy" and more user friendly, but as a technology it simply isn't so.

With NMEA2000, when you want to connect two devices, you just connect them with twist lock connectors. There is no soldering, crimping, or other things that can go bad. If you add another device later, you just install a T connector and you're done. It doesn't get easier than that.

I chose 3210 specifically because it has the "old" Garmin interface which I find much clearer, easier to use and more flexible. New interface is aimed at, how shall I put it, people who don't really navigate well, I guess.
NMEA 2000 in my personal opinion is a protocol that is a "solution looking for a problem", and is not useful at all on a sailboat. (That and serial protocols are considerably more resilient in face of marginal connections and variable power conditions often encountered on a boat than Ethernet).

|funsailthekeys||All the connections on the 3 series are LAN connections except for power and the GPS. I guess that is the right terminology.|

If I were buying any electronic today, I would insist on NMEA 2000. It is much easier to connect things, no need to cut and splice, etc. So if the newer unit supports NMEA 2000 and the older unit doesn't, that would make my choice easy.

I have dual 3010's on my 45' sloop, one up at the helm and one down at the nav station. With the GMS port expander there isn't anything it can't do. There is even a remote available for it,(can't imagine why). With 2 plotters one will automatically go into slave mode. The touch screens have issues being in direct sunlight down here in Florida. I have been using the 3010's since 05' and have about 10,000 miles on them without a problem. The XM weather works as far as St Thomas and with the up graded Gsd 22 the sonar works better. I don't know what you will get for spending the extra money on a 4 series system. Good luck in your choice.

|JiffyLube||I have the 3210, and I've played with the later models. The one thing I find easier to use on the later models is touching the screen to get information or to set waypoints, but I don't care for the screen being cluttered with touch buttons. The 3210 screen scrolling feature would be better if it was a ball mouse, but I've read that there are problems sometimes with the ball mouse on the Raymarine plotters.|

I've got a 3206 and I love it. It has more features than I need and is upgradeable (is that a word?) with radar, weather overlay, whatever you'd like to add down the road.
As I understand it, the big difference in the two lines (32xx/42xx) is that the 42xx is NMEA 2K and the 32xx is the old tried and true NMEA 0183.
Others will be able to shed more light, I'm sure.
