Thread: Multiple maps on nuvi 1XXX series

I have a little issue on my nuvi 1490T.
I've put several maps in SD/map directory but if I look in Tools->Settings->Map->Info some
of the maps titles appear twice, like Anavasi RoadMap:
Anavasi RoadMpa(c) AnavasiDigital
[1] Greece
Anavasi RoadMpa(c) AnavasiDigital
[1] Greece

Also when I replaced one of the maps with a newer version, OFRM Geotrade City from 5.11 to 5.20,
both appear in the list even so only on file is present in SD/map directory:
OFRM Geotrade City V5.20 LAT
[1] OPFRM Geotrade City 5.20LAT
[2] GMapToll All

I can see maps ok if I select them from the list, so the functionality don't seem to be affected.
But it annoys me :D

I move out the img files for those maps from that directory, restarted the nuvi, put them back, but again they show twice.
Is any text file where garmin is keeping this list of maps? so I can edit it manually?
Or any other ideeas?

thanks
