TechReviewSource.com posted a review on the TomTom XXL 540S

The new TomTom XXL 540S is a dashboard GPS navigation device that has a 5-inch touch screen, a nice dash mount, and other valuable features. It does, however, lack a few features that other similar GPS units offer, such as live traffic updates and an integrated MP3 player.
