Speaking of keeping you safe, the nüvi 680 lets you make hands-free calls so you can talk freely during your worry-free driving. By integrating Bluetooth wireless technology with a built-in microphone and speaker, you can pair your nüvi with any compatible Bluetooth phone and talk hands-free while staying focused on the road. You no longer have to fumble with your phone's handset to answer a call or dial a number, just tap the 680's screen and you're instantly connected. And with 1-touch dialing for your POIs, you can quickly and conveniently call ahead to make reservations or get needed information.
In additional to all this functionality, the nüvi 680 includes many must-have entertainment and travel tools such as an MP3 player, an audio book player (subscription to Audible.com required), and a JPEG picture viewer so you can take your favorite music and pictures with you wherever you go. This unit also features a world travel clock with time zones, a currency converter, a measurement converter, and a calculator so that wherever you travel it will be easy to know what you are getting and keep track of your costs. The MP3 player lets you browse music by artist, album, and/or song, while the optional audio books may be purchased from Audible.com which features over 70,000 hours of audio programs. What's more, the nüvi 680 allows further customization via optional software such as a travel guide, savings programs and language translation on plug-and-play SD cards for all your travel needs.
