The Anywhere Travel Companion (ATC) from Control Vision is taking on Garmin's 496/495 for bragging rights as the most capable portable GPS navigator on the market. Pittsburg, Kansas-based Control Vision claims its ATC has a significantly larger screen (4.3 inches vs 3.75 inches) and roughly double the resolution. Priced at $895, it is available with optional XM Weather and Pocket Plates approach charts for $1,895. (An introductory discount of $200 is in effect.) The ATC comes standard with Sanyo's StreetNav navigator and needs no external antenna or wiring. A year's worth of Internet-downloadable database updates is included.
