Garmin Fantom 18
Hi, I just bought a brand-new Garmin Fantom 18, which might have been an expensive mistake. I am having no luck getting it to work on my Rasberry Pi 4 with OpenCPN 5.6.2. It just sits at "scanning interface" and I never get any status lights on the radome. I have tried shorting pin 5 to ground, but it doesn't ever seem to do anything. Anyone have an ideas?
Yes, I know this isn't a software bug/issue, but the community is pretty small. I am a developer and have this running in my home lab at the moment, so i can help with any troubleshooting or other information gathering if needed.
Thank you!
I don't think the Garmin Phantom is compatible with radar_pi yet. If you want to do the reverse engineering you will certainly need a Garmin plotter so that you are able to control the radar dome. I did this work for the Garmin xHD and can be of assistant if you give it a go. I don't think even the xHD 2 is fully compatible with the xHD radar.
In for a penny, in for a pound. I ordered a GPSMAP 742 (the cheapest I could find) to do the reverse engineering. I have an oscilloscope and a decent home lab, so hopefully we can contribute the info back to the community.

@dpeckham any luck yet, do you need any help with the source code?
Hi. I have all the hardware but won't be able to work on it again until February as I will be crossing the Atlantic in January. I was able to get it partially working already, so I am sure it's going to work with a little effort.
