Hi scottscraig,

And oh dear, oh my ... . So you deleted the map from the sd card? Or is there a sd card in nuvi 855 or has it a HDD?

OK, I had a look about the specifications of the Garmin Nuvi 855 and it uses an sd card. And therefore I am afraid that you cannot restore the deleted files. They are lost.

But the good news are (maybe) that you do not have a $175 worth of paperweight. The maps can be loaded from this forum, first of all, there is a thread called [Only registered and activated users can see links. ]. You can request the lost map from there. But first try to find if the map -link already exists in this forum ([Only registered and activated users can see links. ]).

Also, you might find the new version of the lost map from here, so you probably do not that old and lost map anyway.
