Maestro 4250: Magellan's top-of-the-line unit rocks a 4.3" wide LCD display, live traffic (subscription required), voice recognition, AAA TourBook data, Roadside Assistance information, text-to-speech, 6 million points of interest (POIs), and Bluetooth. The 4250 will ship with pre-loaded maps for the lower 48 United States, Hawaii & Puerto Rico, Canada, and Alaska. Available in October for $499 list price. So basically, the 4250 is identical to the 4050, but increases the POI database from 4.5 million to 6 million, has a thinner design, and costs $100 LESS.

Maestro 4220: the 4220 lacks AAA TourBook information, Text-to-Speech, Bluetooth, and Voice Recognition, but adds maps of Mexico. Available in October for $549 list price.

Maestro 4210: Just like the 4220, but includes AAA TourBook data and no Mexico maps. $449 list price.

Maestro 4200: No Canada or Alaska maps, no Mexico maps, 1.3 million POIs, no TourBook, Text-to-Speech, Bluetooth, Traffic, or Voice Recognition. $399 list price.

All in all, basically a re-hash of Magellan's previous units in a thinner case. Although I suppose you can never be too thin, and for those of you looking for a Mexico-U.S. friendly GPS, Magellan's Maestro 4220 will be welcome news.
