In post #156 I see you have a nüvi 610. This model is not able to recognize more than one map file on an SD. You could put one map on SD (as SD:\Garmin\gmapsupp.img) and use the other one from the internal memory of the nüvi (as nüvi:\Garmin\gmapprom.img).

Alternatively, depending on internal memory space available, you could put both there (one as nüvi:\Garmin\gmapprom.img and the other as nüvi:\Garmin\gmapsupp.img).

Note: in the above instructions, replace 'nuvi:\' by the drive letter assigned to the nüvi by your computer.
