I used voice on my 770 for the first time a month or so ago, and was surprised at how well it worked. Going to upgraded to a newer/bigger model later in the year. Taking a shortish (5 hours) to Nashville, with no real need for GPS to NIRVC for Rettrobands, but for sure before I take a 2.5 week trip to Florida in October, I'm going to upgrade. Just holding on in case they come out with another new model between now and then.I cannot recommend it higher, it is a fantastic GPS with free map updates, traffic integration via your connected smartphone, all the campgrounds in the system, voice control, shows truck stops vs. just gas stations (have to customize your sidebar to do this), up ahead info is great (bladder planning), reroute suggestions based on real time traffic. It is simply awesome!
