On my Nuvi 260, as I passed a school zone, the name of the school used to appear on the green bar on top of my unit and also turn red.......that doesn't seem to work on the 1390t.
My previous Nuvi 760 used to state the name of the School I would be passing. My newer Nuvi 3790T does not do this. I think this must be a function of the mapping system because during school times the posted speed limit goes to 40km per hour.
