July is upon us -- do you know what that means? For starters, it's Canada Day, but secondly, today marks the first day that turn-by-turn capable GM vehicles as old as 2006 can search for destinations using Google Maps and have those destinations beamed directly to their vehicles. The OnStar eNav feature is now fully Google-fied, and we're desperately hoping that other factory navigation systems take notice of the awesomeness and begin to do likewise in the not-so-distant future. Till then, have a peek at the GM demonstration vid just past the break, and feel free to let us know how it works for you in comments below.
