Each unit has been ruggedized and made shock-resistant to handle the off-road abuses encountered on the roads less traveled. Each unit is memory-card-compatible with Lowrance's FreedomMap software and MapCreate topographical software. WHY IT'S HOT: Both models are capable of navigating motorists from nowhere to anywhere by delivering full 12-parallel-channel GPS and WAAS reception provided from the ruggedized external LGC-2000 Baja receiver/antenna for super-fast satellite lock-ons and enhanced position accuracy to 3 meters. The GlobalMap Baja 480c features the new Lowrance 256-color TFT display, which provides super-wide viewing angles and fluorescent cold-cathode backlighting. The GlobalMap Baja contains a 5-inch-diagonal 480x480-pixel LCD screen for excellent glare-free viewing through a high-contrast Film Super Twist monochrome display with 16-level gray-scale definition and advanced white LED backlighting.
