Yeah it was a USB dongle, I think Garmin made it, and it was a huge pain to set up. Power inverter into the car charger, laptop into the power inverter, Garmin dongle into the laptop, load up the software and wait like 10 minutes for it to triangulate itself with glonass or whatever other satellite options were in there. After that it worked pretty well, but most of the time I could get to where I wanted to go before it could figure out where I was.
The original Droid was the first one I had that really impressed me, basically because of how much nicer it was than that previous experience. Now I just had to pull out my phone and launch the app, and it was accurate to within a few feet instead of a few meters! Still took them a few years to update Google maps with a lot of the new subdivisions in the area, but for a novelty navigator it was pretty cool.
It’s not active right now, but The Fish Doorbell is a fun one in the spring/summer
