They are still around. I reached out to them about my speedo too.
The LCD on mine is messed up.

I used their contact form and got a response quickly. They asked for the serial number from the back of the speedo. I've since bought a BlueFire adapter as well, so my urgency to fix the LCD decreased a little. Mine is still useable, so I haven't pulled the dash apart yet.
Maybe now that we're parked for awhile, I will put that project nearer the top of my task list.
