Engadget: It’s time for Garmin to refresh its lineup and flood the market with a slew of dash-mounted GPS devices. In total there are six new series of navigators, with countless models scattered amongst them. The “essential” nüvi 30, 40 and 50 (top left) lines come in three sizes: 3.5-inch, 4.3-inch, and 5-inch sizes (we’re sure you can guess which is which), and cover all the basics including a lifetime’s worth of free map updates. Stepping up a notch to the “advanced” 2405 (top right) and 2505 series (4.3-inch and 5-inch lines respectively) nets you Garmin’s Guidance 2.0 system. The software includes niceties like 3D traffic updates (for free, of course) and photoReal junction view for finding the right lane at off ramps. Last is the “prestige” line — the nüvi 3400 series — ultra-thin, 4-inch devices that looks more like a phonethan a navigator. The 3400s turn in the frustrating resistive screen for a capacitive panel and upgrade to Guidance 3.0. The 3.0 edition sports all the same features as its lower numbered sibling, but adds pinch-to-zoom, lane guidance and text-to-speech for incoming SMS messages. Not overwhelmed enough yet?
