Hi all. newby here.
My Montana 750i does not show my Custom Maps loaded onto my 32gb mSD card. The name of the directory is Garmin/CustomMaps/. Files are KMZ (and KML) I loaded them via a USB connection to the computer. The KMZ open from the Montana in Google Earth Pro (GEP) but KML is not seen.
I wondered if I have to actually save the files through GEP but that seems silly.
My waypoints are also loaded on the mSD card in the proper folder Garmin/GPX and they appear fine on the Montana.
Any clues? Ta
