Remember that roadside barbecue joint in Texas where you had the ribs that changed your life? Can you remember the address? Did it even have one? It´s no problem for the Navman iCN750 [above]. Just pull the battery-equipped device from its windshield mount, snap a picture with the integrated 1.3-megapixel camera, and the unit will store the photo paired with the location´s GPS coordinates. The next time you´ve got a hankering for ribs, go to the NavPix menu, select the shot, and the 750 will guide you back. You can trade pics between 750s or offload them to a PC with a USB cable or an SD card. The gadget has room for about 5,000 pictures-enough for a cross-country barbecue safari. Don´t forget the Wet-Naps.
