Hi. I have a new (to me)Tom Tom One (Original...has maps on SD card), and I'm having trouble planning destinations located in New York City. It was purchased as a refurbished unit. I've plugged in several different zip codes, but it keeps responding that there are no street names. Even when I type in the city and receive "New York, New York", or "Manhattan, New York", it has not street names. Any suggestions or known glitches? Thanks to all in advance.
