Loading Custom Maps from mSD

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

    I'm starting to worry about the ability of the GPS to load Custom Maps.  I moved the maps from the mSD onto the internal storage.  They still do not show up.

    In my case the waypoints are more important but the maps would be useful.

    I've also noticed that the log in procedure loops sometimes.  And log in can take an inordinate amount of time.  I can't work out reasons.  At one stage I had to take the battery out to turn it off as well.

    I've read the issues posts dating back some years and am concerned that Garmin is not serious about these very expensive handhelds.
