Garmin HUD support
Purpose of this project
Garmin created fantastic Head-up Display, but they had it discontinued in 2015 src. Fortunately, whole protocol had beed reverse engineered. This allowed community to createte their own works.
Works
Project started in Aug'23 as simple solution to connect GMaps with Garmin. PoC was created with python (can be viewed here) as it is the quickest known way to test protocol and create objects. With the help of Garminuino and GMapsParser first version of application was created, which wasn't working at all.
Two weeks later I switched to Mapbox as completely standalone solution. Despite some bugs and huge battery drainage some may say that it works.
