As Garmin hasn't made any official announcement, we can't tell you when these sneaky handheld GPS navigators first showed up on the company's website, but say hello to the Oregon 600, 600t, 650 and 650t. Aesthetically, they all look identical, with a 3-inch "transflective color TFT touchscreen" in portrait orientation (240 x 400 resolution). Similarly, they share the overwhelming majority of internal specs, and all track your jaunts into the great outdoors using GPS and GLONASS. The only major differences we can find on the spec sheets are that the t-marked models come with Garmin's "TOPO US 100K maps" preloaded, and that both 650 units boast an 8-megapixel camera. As the Garmin pages note, the models cost between $400 and $550, but they won't be available for purchase until our FCC overlords allow it. Head to the source link if you'd like to know more.
