voice talk like person have marble in they mouth . many name and direction be hard to understand , could not pronounce ` county ' . some address and street could not be find . incorrectly call out road name . sometimes give wrong direction to turn . we feel that we have to have the appropriate map handy to make sure it be direct we correctly . difficult to enter some city\/road name -- after typing in a few of the letter a list would come up , if you name be not on the list , there be no way to override that list . we do not recommend this product , as we feel it be overhype .
