maybe it's because your map does not have the 540x960 resolution?

2 solution:

1. download a map with qHD(540x960) resolution(not sure is it available in MFM or not)

2.
go to NaviSEA(for X5) in your sd card or phone memory, go to organics, choose the highest resolution folder(lets say 480x800) and rename it to 540x960, then proceed to all the folder in the organic folder, if you encounter any folder name is the same as the previous folder that you changed(480x800), rename it to 540x960.

then go to market download "spare part" or spare part plus, launch the app, untick a option with the name something like "run in compatibility mode", restart the phone and woila... papago X5 is running.
