Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
What I suggest is a two step process. First, lets factory restore your G3 Approach device. Heres how.
To perform the master reset:
Once that is complete. We need to turn the device on, proceed through the initial setup. And then connect it to a computer and update its software. To update the software, you need to download and install this program.
Once you have installed the newest version of the garmin express program. Run the garmin express program on screen. It should ask you to connect a device. Make sure the approach G3 is connected and turned on, then click Add device.
It should find and add your Garmin G3.. Once t hats done.
It will check if there are any software updates to install. Download and install any and all software updates it has. Once that is complete. Disconnect the G3. Turn it off, then back on, and reconnect it to the computer.
Have garmin express check for updates a second time. If it finds any , install it.
Once that is complete. You should be running the newest software on a clean device. And that should help your accuracy on the course.
If you run into any issues, or have any further questions. Let me know!
