I be a person that will research online and at the store and this be the best gp I have see . I be about to order the Garmin c330 until I check it out at a local electronics store . the salesperson show I how simple it be to use and I pick it up quickly . when I tell he how cool this thing be and that my mind be make up on the c330 , he say `` wait , check this out '' and show I the c340 . this one actually speak the name of the street instead of left or right at the next corner . it may not seem like much , but the whole reason for buy a gp be to have you hand hold as you drive . since I do not intend to buy another , I spring for the extra $ 70 buck . this puppy be a pleasure to use . I be a field technician so this save I time and fuel when go from one place to another . its especially helpful when I be call to go someplace I have never be before and I do not need to ask direction or refer to Mapquest . I simply pull over from where ever I be , key in the address and I be off . once its save , I can always return to it . my wife have always tell I I get lose after pull out of we driveway , but never again . its size also make it convenient for when I be fly out of state and have to rent a car . you will not be disappoint .
