with this new software version 5.80 on my Nuvi 1300 NT now I CANT choose which map info I want.

After this update, I have had the opportunity to choose between the map installed on the garmin device (CN North America NT 2012.30) or in the external card (Mexico NT 2012.30) but now only appears something lihe this:

(selected) CN North America NT 2012.30
[1] CN Mexico NT 2012.30
[1] Lower 49 States

With no choice to select anithing.

I´m Correct or I have missing something?
