For the most part, standalone navigators have retained their same form factor for the better part of the last five years. Each one looked like the other, with the main differentiators being a fold-out or integrated antenna and a big or small display. With intense competition coming from the smartphone space (yeah, we're looking at you, Google), the bigwigs at TomTom and Garmin are obviously thinking of ways to innovate and keep their consumer PNDs relevant. We aren't exactly convinced that shaping said navigators like said smartphones is the best answer, but you won't find us kvetching about the sleek lines and slim nature of the nüvi 3790T. Announced back in April alongside the 3760T and 3750 models, the king of the 3700 series packs a 4.3-inch WVGA multitouch display and a frame that's just 9mm thick; what you're left with is the most stunning personal NAV system on the planet, and we've had the opportunity to test one out before it hits US shelves in July. Care to see if this beaut is worth $449? Head on past the break for our two pennies (and a video overview, too!).
