You may want to look at the the Eagle CUDA 250 S/map. It is a new model that has all the features of the 240 plus a map. I ordered mine last weekend and will hopefully install within the next two weeks. I will post a reply soon after.

I guess the jury is still out on these units though. We shall see.
