Hey all,
I'd like to bring your attention to a CIQ GPS/Positioning bug in the 10.xx Alpha/Beta releases (10.42 right now). While it is under investigation by Garmin (I reported from the 10.33 alpha but was overlooked until 10.39 Beta report by user), I don't know whether it will be fixed by final release: forums.garmin.com/.../bug-apps-with-gps-crashes-at-start-10-39-epix2
Basically if you're trying to set any GPS :constellations or :configuration the app will crash when you invoke Position.enableLocationEvents. Garmin's own code snippet also crashes. This means that only "GPS Only" works (no Galileo, etc.)
So if you have any app that tries to set :constellations or :configuration you may want to have a version ready that doesn't do that and be ready to push it, should Garmin decide to release the firmware without fixing the bug.
