The TomTom One XL is a portable global positioning unit (GPS) released by TomTom in April 2007. The One XL version was an upgrade to TomTom's basic One GPS model, with a larger screen and improved mapping intelligence. Since introducing the original XL version, the company has released upgrades to their XL line, including the XL 330, XL 340 and XL 350 -- as of November 2010.

The XL version offers the user a 4.3-inch wide LCD touch screen, which compares to 3.5 to 4 inches in other TomTom portable GPS models. The screen clarity of the map and directions are enhanced by the model's original resolution of 480-by-272 pixels. A night vision dimmer can be activated on the display when driving in the dark.


The larger screen adds to the weight of the GPS at 208 grams. Subsequent upgrades to the original One XL model are somewhat lighter at 183 grams.

Processor and Memory

The TomTom One XL has a Central Processing Unit (CPU) of 266MHz and Random Access Memory (RAM) of 32MB. The internal memory equals 1GB, including the memory (SD) card.


Although TomTom offers a SiRF Star III receiver in its other models, the original One XL model came with a Global Hammerhead receiver.


The basic XL model offers loaded maps of the United States (including Puerto Rico) and Canada, although the XL 340 and XL 350 also includes maps of Mexico. The voice option on the One XL allows you to listen to directions and street names, so you won't have to keep your eyes on the GPS unit while driving.


This version uses a lithium-ion battery which offers two to three hours of operation. The unit is chargeable with a USB car charger plugged into the 12-volt outlet. A USB cable attachment is also included so that you can power the model via a computer by attaching it to the USB port.


The TomTom One XL is equipped with a plastic docking station that fastens to the windscreen with a plastic suction cup. The 330 model introduced a portable mount that folds up. The TomTom Home software that is included with the GPS model gives the operator the ability to download updated maps and preplan trips. Bluetooth can also be enabled on the One XL.
