I have a nuvi 1490T with the europe 2011.20 map preinstalled. This map takes a lot of space in the nuvi memory (I have 460mb free). I wanted to load a different map but there was not enough space. I noticed then that I could not find the map anywhere in the folders of the nuvi. It must have been installed in a secret directory which I can't find.
I could use a card but 1. I don't have a card of that size and 2. I would like to see where the map is. Is there a tool to handle such cases?
