I have just purchase the new c330 StreetPilot through Amazon.com . every time I turn it on it give I message : `` can not unlock map -lrb- ok -rrb- '' . the map be not load I be get only basic map layout . I have reset the unit without result . Garmin technical support be unreachable by phone . I be tell it will take they 5 day to respond by Email . this be quite ridiculous situation . I own 3 other Garmin product and those be work fine .
