Yesterday I bought my second GPS in 10 years, a Garmin Nuvi 265W, at Costco. This thing couples with my cell phone via bluetooth as a hands free device, receives traffic info via FM receiver, finds home at the touch of a button, and speaks the directions. Shows police, fire, hospitals, food, gas, closest to me...at the touch of a button. Wow! Liked it so well I've ordered two more for my girls. Still, the compass, Mapscos, and detailed road atlas will remain in the car, along with my trusty Magellan Map 330 and a couple spare batteries. It's got topos on it for hiking, plus I use it in my yaks/sailboat (which also have compasses).
