I upgraded my 2017 with the help of many emails back and forth with Motorguide. I have a Gen 1 system, so they sent me the software (version 7) and I did it. I will be reverting back to the previous version (version 2) as I lost some features I had.
The list below happened after the new software upgrade.
* Lost use of Pinpoint remote
* as long as NMEA cable is plugged in, remote does not work – works when unplugged
* Lost use of cruise control
* ramps up to full speed on 1st button press (should be 1 mph). Unable to adjust speed down – must hit M button to get out of cruise
* No longer have Autopilot on HDS. All Motorguide modules are detected after Network Auto-config, but if I click Goto cursor on chart a message is displayed that no active autopilot is present.
Motorguide sent me version 2 software. If that does not restore my lost features, they want me to start troubleshooting the NMEA, and/or gateway. I will not purchase another $250 cable, because their “fix” broke it.
Hopefully I can find out after this cold snap, and other chores to catch up on…
