For improved GPS satellite reception and accuracy, you can try these tips.
Wear the watch on the wrist near the middle of the car instead of the window.
This position orients the GPS antenna for better reception.
Connect your watch to the
Garmin Connect™ app using your
Bluetooth® enabled smartphone.
While connected to the
Garmin Connect app, the device downloads several days of satellite data, allowing it to quickly locate satellite signals and provide predicted satellite positions.
Take your watch outside to an open area (away from tall buildings and trees), start a
Race activity, and wait while the watch locates satellites.
After locating satellites, wait an additional minute to download current orbital parameters to improve accuracy.
NOTE:Carbon fiber cars can block and absorb GPS signals. Interference from carbon fiber cars can affect the accuracy of the GPS antenna.
