I was able to load *.mgln files created with "Magellan POI File Editor" version 4.1.1.0 - the one which is on the original CD, coming with the 3225 unit.
Destination of the file:
1 - when you load into the unit internal memory, manually or using the
integrated transfer function from the Magellan POI File Editor:
"drive":/TFT/USR/CPOI/filename.mgln
It may need a RESET of the unit. However, every time when I unplug the USB cable from my PC, the 3225 unit reset itself.
I noticed that when I tried to use the transfer function of Magellan
POI File Editor the default path where the file *.mgln to be saved it
was WRONG !!! it gave me:
"drive":/TFT/USR/CPOI/filename.mgln/filename.mgln
instead of "drive":/TFT/USR/CPOI/filename.mgln !!!
2 - when you want to use the SD card copy, the *.mgln file in the "root" = No need for any folder !!
I am using and old 32 MBytes SD card (Panasonic).
Note:
- before you do any changes to any internal files, do a FULL back-up of
the 3225 unit - copy all files and folders. I see the 3225 as a
removable memory of 2Gbytes - aprox. 800 Mbytes free there !!
