Engadget: If you’re a fan of TomTom’s Go Live series of nav units, you’ll get a kick out of what the company announced today. Hitting retail and online stores in October is “the world’s first portable navigation device with a suite of popular travel apps,” the Go Live 1535M. That’s right folks, this piece of dashboard flair will allow you to use Yelp, TripAdvisor, Expedia and Twitter all from the comfort of its 5-inch touchscreen. In addition to the new application integration, the GPS juggernaut’s classic features will be available as well: hands-free calling, real-time traffic info, local search, fuel prices and weather forecasts. Sounds great, right? But what’s that… you already sprung for the 2535M model? No worries, mates — you’ll be able to download the new features this fall via software update. Pricing for these app-enabled navigators will start at $250 which includes a free 12-month subscription to TomTom Live services. Pretty soon, you’ll be able to make that dinner reservation while TomTom tells you how to get there, seconds before you tweet about it.
