I have 2 of them, just finishing 2nd year with them. I'm quite satisfied with them! You can read about my entire setup (including the M7's) here:
http://www.cruisersforum.com/forums/f13/...06605.html ( I should probably post that to this forum as well
)
I had 1 that got some water in it somehow near the end of the first year, Warranty replacement/fix was no issue. Went through a couple rainy days both years, no issues with touchscreen in wet conditions.
Keep in mind, unless you are flush mounting them, you'll need the backplate as well. Biggest issue I have is with 3 monitors, that's 9 cables (3x power, hdmi, usb) to get to the computer. Have yet to figure out a "clean" way of doing it...
I haven't tried that one but if you are looking for a less expensive diy solution and you are a bit handy.....

This is what I use and so far its works great. I have a cad file for a housing if you want that ... its not 100% waterproof though

Is it difficult to waterproof a computer board?
Will this method of soaking it in nonconductive epoxy
work with it?

I’ve also read people use FayTech displays
but they have no speakers which you want for anchor
alarm and collision avoidance.

Waterproofing with epoxy can work for sealing electronics, though you need to keep in mind heat management. If you lock in the heat the board will overheat (not good!) With a low power monitor you may get away with it? Anything with a CPU (raspberry pi etc) though will likely overheat.
As for speakers in the monitor, my Faytech has some. That said every monitor I've seen (marine or otherwise) with speakers in it the speakers are garbage. Also you will need to leave the monitor on all night for the anchor alarm? I'd suggest instead to wire the audio out of whatever computer you're using to either your boat's audio system, or maybe another dedicated speaker system? (USB Speaker, Bluetooth etc)
Epoxy seems good for heat dissipation. From what I read better that enclosed air
It would be interesting experiment with pi4 to coat it with non conductive epoxy layers and then with heat dissipating one which has some metals in it. And put a radiator heat sink in it. Could it work just as good as ventilating cooler?

D'oh, completely forgot there already exists something better than epoxy. Do a google search for "Conformal coating".
Still need to be careful with heat, though you could probably add some passive heatsinks to the cpu/etc before applying the coating.
I’ve got chance to play a bit with Argonaut
m7 gen 2 and pi 4 with openplotter 2 beta.
1. Screen resolution is a bit low 800x480. 480p
But it’s workable
2. Touchscreen support from Raspbian and OpenCPN
way poorer than on Android.
Only one finger touch.
No double click emulation.
No on-screen keyboard.
3. No speaker built in into M7 monitor
It seems if you have 3 choices for a cockpit
universal display
1. Windows PC stick with Open CPN in cabin
and touch HDMI display in cockpit
2. Android Tablet with Open CPN in cockpit
and some kind of NMEA multiplexor in cabin
(KPlex)
3. Openplotter in cabin with HDMI touch display
in cockpit.
due to poor support of multitouch in Linux
option 3 so far looks least attractive.
I haven’t tried first 2 though they might have
their own drawbacks.
How do you set up touchscreens with multitouch
for a cockpit with OpenPlotter 2? I just
couldn’t figure it out.
thanks,
