Portable navigation devices are letting users program alerts to prevent speeding tickets or highlight spots they may want to stop, displaying that information on larger screens. Garmin PNDs and handheld GPS receivers like the nüvi 200W now have sunlight readable 4.3-inch color touchscreen display on units that measure less than an inch thick. The 200W also has enough memory to store points of interest that are useful beyond helping drivers find their destination. Fast drivers can set proximity alerts that warn them to slow down when they're nearing school zones and roads monitored by safety cameras. The 6-oz unit uses the STMicroelectronics Teseo GPS engine to quickly power up and provide accuracy down to two yards.
