NMEA 2000 Device Score Card

At various times I've made comments about how frequently I find problems in the NMEA 2000 interfaces on devices.  A while ago I made a rough tally, but decided it would be good to be a bit more methodical about it.

So here's a table showing all the devices I've worked with, where I found problems, and most importantly which ones have been fixed.  When issues have been fixed, I have included the software/firmware revision that resolves the problem(s).  I'll do my best to keep this up to date, and if anyone hears of fixes, please let me know.

Please note that just because a device has issues with its NMEA 2000 interface doesn't necessarily make it unusable.  Many of the problems only show up under certain circumstances, and many times the problems do not completely impair operation of the device, or can be worked around in one way or another.  I continue to use a number of the devices below even though they still have problems.

Also please note that this is just about the device's NMEA 2000 interface, and not about other aspects of the product.  I've reported on a number of other products that have serious issues, but they are not directly related to the N2K interface, so not reported here.  Maybe someday I'll do a score card looking more broadly at products, but not here and now.
