On the Nuvi 1490T, I had put 2 separate files for 5 metre contours and 10 metre contours. When looking at map info page, I see that the 2 separate files are listed under one entry (which has the name of one of the files) Under the name there are 2 entries. [1] list the first individual tiles names of one map set and [2] list the first few tiles names of the second map set. There is only the one check mark and hence both maps are on or off but I can not change one separately! The maps are by the same author.

Has anyone have any ideas how the individual maps can be selected and seen??
