Thread: HOW TO REVERT A US-GARMIN (nuvi 1450 or other 1xxxx) INTO A EU-GARMIN UNIT

I recently bought a 1490 in the US and also converted it to EU use. Here is what I did:

006D135900.gpi was not on my unit
fs_image.ver untouched
gmapbmap.img untouched
gmapbmap.sum deleted it, will be recreated by the unit in diag mode
gmapprom.img REPLACE WITH gmapprom.img (size:2.168.640) of the CT EU 2011.40 XT
gmapprom.sum deleted it, will be recreated by the unit in diag mode
gmaptz.img untouched, will be updated by webupdater if old
gmaptz.sum deleted it, will be recreated by the unit in diag mode
Locales.xml untouched, will be updated by webupdater if old
TrafficProvider.xml untouched, will be updated by webupdater if old
.System\SQLite\D233000.db not used by 14xx

Your procedure should work ok.

Some info:
006D135900.gpi - it's POI file with MSN_Airport for work MSN flight infoservice in USA. No MSN subscription - no needing in this file.
.System\SQLite\local_poi.db - your personal setting for POI building in maps if you made it (you can exclude POI from seaching or change telephone number, and other function by manual), if you delete it - will be rebuilt by unit only empty database.
.System\SQLite\mlg_history.db - file for diagnostic info (for service), if you delete it - will be rebuilt by unit only empty database.
.System\SQLite\system.db - file for system info (it have records for some setting and after deleting may be need make this setting again), if you delete it - will be need to make this settinf again. Deleting of this file often help to solve problem with wrong setting.

D*.G2S used for TRAFFIC TRENDS compability unit with corresponding version of map. But is used in case if you send info for TRAFFIC TRENDS to Garmin. In this file no personal data and it same for all device, only necessary database SSID for online wireless connecting to server?!
