The TomTom XL 340 and XL 340-S are similarly featured mid-range widescreen GPS devices. The XL 340 is exactly the same as the XL 340-S, except for the added text-to-speech functionality, which is used for street names and places. The TomTom XL 340/340-S sports a black bezel with chrome trim, unlike its predecessor (XL 330/330-S), which was outfitted with a gray design. Both models feature a 4.3” LCD screen and a removable suction-cup mounting bracket. Improvements in the XL 340 line include a “Quick Menu,” which allows fast access to up to six common GPS functions. Maps have been improved, including seven million points of interests across the U.S. & Puerto Rico, Canada and Mexico. XL 340 owners will also get “Advanced Lane Guidance,” which shows what lane the driver should be in. Live traffic is not included; one must purchase a separate traffic receiver and also pay a yearly subscription fee.
