I just brought a LM50 device.

The map inside device is not updated and I try to update it online from Garmin with providing serial number of the device.

But compare to my Garmin Mobile XT, it seem to be less POI and road is outdated.

1. I have no idea what is the different between the NT map and MFM map, anyone can explain to me?
2. What if I copy "gmapsupp.img" file to my device, will it work?
3. What will I lost and gain if using MFM map? all the junction view will no long exist?
(Well I understand Mobile XT dun have function view)

Thank you.

The former is compiled by Garmin and is released quarterly while the later is compiled using 3rd party compilor and is released weekly

Newbies should copy it into SD card/garmin sub-folder

MFM map does not have Junction View but it is updated weekly

Thank you.
