Software update not loading to a GPS 152/152H marine chartplotter
Before transferring an update from the computer to the device, the baud rate must be changed. After selecting the updater file or the execution file, a window displays with connection settings. The default setting for the baud rate is 115200. Change this setting to 38400 and then try to download the firmware update to the device.
If the update still does not download to the device, please check the Comm Port setting on the device by following these instructions:
- Press the Menu button two times
- Highlight the Com tab on the left hand side of the screen. If the Com tab is not visible, keep scrolling down until it appears.
- Press the Right arrow button one time to highlight the setting for Serial Data Format and press the Enter button
- Highlight Garmin Data Transfer and press the Enter button
At this point, the device should be ready to receive the update. Please try to run the update on the computer one more time.
