I discovered a new nuvi trick today while perusing some YouTube video reviews. Say you’re deep into the menus, perhaps entering an address, and you want to go back to the main menu. Instead of hitting the "back" button numerous times, just hold it down.
Maybe this is a well-known tip that I had just missed, but it’s new to me. It works on my nuvi 660 and, according to this YouTube video, it works on the 200W. So I’m assuming it works on all models. If you try it out on a different model, let us know in the comments section below.
