Intrigued by those XL IQ Routes edition 2 navigation units TomTom rolled out for Europe back in March? Then it looks like you'll soon be able to get your fix in the form of the XL 350 and XXL 550, which recently turned up on TomTom's US website. In line with TomTom's usual naming convention, the XL 350 and XXL 550 pack 4.3-inch and 5-inch touchscreens (non-capacitive), respectively, and are each available with your choice of lifetime maps and traffic options. You'll also get 7 million POIs on each, along with advanced lane guidance, spoken street names, maps of the US, Canada and Mexico, TomTom's EasyMenu interface and, of course, the company's IQ Routes technology. Look for these to set you back between $169.95 and $259.95 depending on the model and add-on options.
