This one will get you there! After reviewing about 10 GPS car navigation systems I chose this one. The Garmin Street Pilot c320 is easy to use,
failry accurate in locating restaraunts in the area, (some restaraunts that closed years ago still show). Excellent at locating street adresses and gas stations. The low price is also what attracted me. This one cost me about $350 with S/H. I priced many and even a comparable model at local stores sold for over $500.00. I have used mine in the Santa Cruz mountains
and it does throw it off. However, the mountains tend to block sattelite signals in general. I have had it show me on a parallel road, off road and stop short or long for 1 mile. It also has an annoying way of telling me to turn around when I passed a destination. I do use this for business and use it extensively. Most casual users will not run into these problems. When this one losses the signal it often regains it within a mile or 2 and recalculates. It is very easy to move from 1 car to the next. It runs off battery for a day or so. When you compare other GPS systems to this one. You'll see that for $200.00 to $1000.00 more your not buying much more of a GPS, your just spending more money.
