Just downloaded and installed new 870 map for my 2535 Live and WOW what a difference it makes. All of a sudden, it flies thru menus, screen to screen, looks like they finally optimized maps for a new software. I didn't check it on the road yet but tomorrow morning I'll be going all over NY so it will be a good test. It downloaded and installed without a single hiccup, so I hope it finally becomes my primary PND.
