After a full cold start I am able to replicate this problem: I am in the Eastern United States, and the gps coordinates for my location (when the gps has full view of the sky and reports 8 satellites found) are correct for latitude but off by 0.665 (decimal) in longitude (at least 60 miles from where I am). The longitude changes as I move the gps to different locations, but it’s always off by this significant amount. I’ve verified my coordinates with multiple other sources (including Google Maps, Apple maps, my mobile phone, etc.) - it’s the rephone gps which is incorrect. I use fcc.gov/media/radio/dms-decimal to convert the decimal values to degrees minute seconds for comparison to other devices.
