Thread: Multiple maps on Garmin nuvi 2545 LM

Hello everbody,

andbody with expirience adding multiple maps on Garmin nuvi 2545LM, with this combination, gmapprom.img on internal memory .System folder - original maps installed by Garmin distributor, was there when device is bought, and 2nd map on micro SD Card in folder Map on root of SD Card with name gmapsupp.img, cause this is described in Garmindevice.xml like a path and name of supplement map.

So, is this combination possible, ORIGINAL Garmin 2013.21 map on internal memory gmapprom.img - original map by Garmin installed, and on sd card Adria Route 4.10 gmapsupp.img - unlocked by Garmin Unlocker?

When devics recognizes 2nd map on SD card, show message necessary restarting to reload maps, and after restart it try to recognizes 2nd map, but then show message "can't unlock maps", so what can be there? Maybe it can recognize Adria Route 4.10, cause isn't unicode map or whatever? I tried to make 1 country from Map Source from 2013.21 map and to add on SD Card, on same way, but same message "can't unlock map", even Map Source 2013.21 is unlocked!?

If somebody has some idea, suggestion, please post it...
