Though TomTom GPS units do not generally receive the same accolades as Garmin's similar products, the ONE XL features a distinct advantage over the Garmin Nuvi 255W. Otherwise, the products are nearly identical, save for appearance and pricing.
Bluetooth Connectivity
The TomTom ONE XL includes Bluetooth connectivity. While other Garmin Nuvi models include this feature, this is not the case for the 255W.
Physical Appearance
The screen sizes of the ONE XL and the 255W are identical; each has a diagonal measure of 4.3 inches. The ONE XL's finish is silver, whereas the 255W has black accents and a pure black finish. Both models include a windshield mount.
Overlap
Many similarities exist between the 255W and the ONE XL. The list includes, but is not limited to, preloaded maps, points of interest (POIs) and multiple routing options.
Pricing
Unless Bluetooth connectivity is worth over $200 to a consumer, they are better off purchasing the 255W. It costs $180 in comparison to the ONE XL's $400 price tag. Prices are as of September 2010.
