Garmin StreetPilot c340 Car GPS Receiver

Overall outstanding unit in which you should be pleased.  Power cord comes apart (something that has happened to me twice.)  The tip of the cigarette lighter plug simply falls off during normal use (after less than a year).  When making a turn, directions sometimes come with too little distance left to safely make the turn.  The c340 is almost always accurate in knowing where you are and how to get you there.  However, there have been two times when it "lost its mind" and sent me to the wrong location.  I had to restart it to get it working again.  I would give it 5 stars if it weren't for the poor quality of its power cord.
