Have been using over 10 years different generation of Garmin GPS watches. The latest I am now using is 245. For the last 10 years, the GPS does not work accurately and has been consistently wrong in the area near the west Kowloon cultural zone. This is due to the GPS chip issue. However, as the chip has been improved over the years, i wonder if the unit for managing the GPS chip can explore if the inaccurate GPS issue can be remedied by now?
