I have a nuvi 2555LMT unit, and i added it to Garmin Express. I inserted both a 4gb and a 32gb microsd card into the unit, however Garmin Express does not show either when I go to tools, the external memory does not show up and it only shows device storage. Is this normal, or does Garmin Express not show external memory. If not, I think it should.
Also, what the the max size microSD card that this unit can support.
ps.. i formatted both cards using Fat32.. so I hope this is correct
thanks in advance
