FTM-350 / Navi - not working, radio stays in standby
"Navi" won't work, radio stays in "Stdby" - Radio needs to be set to GPS. Go into "Radio Menu Settings", select the APRS/GPS tab, in about the center of the page, "My Position" needs to be set to GPS, so the radio can tell where you are to navigate or "Navi".

We have also found that the radio struggles to "Navi" or navigate over about 600 miles.
