Thread: City Navigator Europe 2011.20 - Mapsource+ countries IMGs

before deleting must always make a backup on pc
but you dont reply, how did you name it? In internal memory the map must be renamed gmapprom. img and if you have an old gmapromm.unl delete it or you wont see the new map-

I have a 1490T, I have sqlite in system/sqlite directory. What is sqlite ? I have 2011.10 installed and my *.db file is very small compared to the one posted by Giuseppe 66 in post #75. Should I install it if I upgrade to 2011.20 ?

files in.System\SQLite folder. In this folder there are files with .db file extension.

* D232800.db
This appears to be the trafficTrends North America data, according to the garmin_metadata table in the db. It might also be just metadata that the system uses to find the actual data somewhere else on the nuvi. There is a table called SpeedProfile that has the columns SSID, TimeID and SpeedSamples.

* local_poi.db
I think this one is storing the information when you rate a poi and possibly mark it as not valid, etc.

* mlg_history.db
This appears to store the ecoRoute data for your driving habits. The history table has columns like acceleration score, speed score, deceleration score, etc.

* pre.db
This appears to store the myTrends data and "pre" stands for prediction. There is a table in this db called prediction that contains the stats for its "predicted" routes.

* system.db
This db is used by the system to find the other tables. It has only one table called system, that has two rows. One points to D232800.db and has the description of trafficTrends™ North America. The other one just points to the mlg_history.db file .

* user_strings.db
This is where the predictive text is stored when you enter in addresses or search fields. The table user_string contains the string_data column (i.e. Best Buy, San Diego) and the context column contains a numeric value that matches to whatever screen you were in when you entered the value. There is also a usage_count and time_stamp column, probably so it can remove old and unused values when some pre-determined amount of values are stored.
