The super-bright, 4.3-inch (diagonal) touchscreen display gives is anti-glare for ease of viewing during the day and automatically changes its color profile for easy viewing at night or in dim light. It offers 2d or 3D perspective views. The widescreen format gives you 70% more actual screen area than a 3.5-inch screen. Primarily this translates into a better view of the area through which you are driving. This is especially useful in showing you what parks, restaurants, ATM, gas stations, etc. are nearby, or in letting you know whether a detour is a good idea. Also, the device itself is larger, meaning controls on the screen are more widely spaced and somewhat easier to push.
New Features -- Multi-Destination Routing
This lets you enter several spots into the device (day care - supermarket-cleaners - office - day care, for example) and it will plot the fastest route. And once you've found the best router, the "Route Planning" feature lets you save up to 10 different routes, Garmin gps touts the feature for providing, "the most efficient route for errands, deliveries and sales calls." The feature also makes this an instant essential accessory for anyone who shops garage sales (you know what we're talking about).
New Features -- Where Am I? Where's My Car?
The nüvi 700 series is the first to answer two common questions: "Where am I?" and "Where’s my car?"
At any time, with a single tap of the screen, drivers can display their exact latitude and longitude coordinates, the nearest address and intersection, and the closest hospitals, police stations and gas stations. And to help drivers find their car in an unfamiliar spot or vast parking lot, all nüvi 700s automatically mark the position in which they were last removed from the mount.
• Optional software for language translation, detailed travel guides, and savings programs allow you to customize your nüvi GPS unit to fit your travel needs.
• The FM transmitter feature is only available in the United States, Canada, Australia and New Zealand
• Like most USB Mass Storage Devices, the nüvi is not compatible with Windows 95, Windows 98 or Windows Me.
Hands-Free Calling
In more and more places, it is becoming illegal to use cell phones while driving without a hands-free kit. WIth Bluetooth capability, microphone and speaker, you can match your nüvi to any bluetooth-capable phone to make hands-free mobile phone calls. Simply dial the phone number with the garmin nüvi's gps touch screen keypad to make a call on a compatible phone. To answer an incoming call, just tap the screen and speak into the built-in microphone. Making and taking calls on the road has never been easier, or safer. In addition, Garmin makes it a breeze to look-up and dial numbers from your personalized phone book or even tap into your cell phone's call history log.
Customer reviews
Better than the nuvi 660 
I own both the Nuvi 660 and the 760, I'm writing this review for people having trouble deciding between the two as the price difference between the two products at the time of this review is about 100 dollars. I'm not going to focus on the feature differences, as that information can be easily obtained from specifications and online reviews. The 660 was a fine product back in 2005-2006, but the new 760 outdoes the 660 in practically everything, but there are some key usability fixes that make the 760 a better buy for the frequent user.
Highly Recommended 
This unit is replacing a nuvi 360, which is going to my sister. The nuvi 760 is still a bit hard to find. I found one in stock at a local SoCal retailer on 28-Oct.
Overall, I like the new compact form factor. There have been concerns expressed in various forums on the sensitivity of the internal antenna. So far, it seems to be sensitive enough. Side by side, signal strength and accuracy of the 760 are maginally better than my old 360 with the pop-up antenna. I'm getting 21 foot accuracy inside an office, a few feet from East facing windows. Attaching my external antenna to the MCX connector gives 9 Foot accuracy with 10 satellites at full signal strength.
