Summary: This was my mistake: this unit has no battery, so it is only alive when the car runs. If the car's engine stopped and you start it again, your unit will re-initiate. Another inconvenience is that you need to specify the narrow region you are driving in. As you move from NY to MA, for example, you get lost since the two sets of the maps - for NY and MA - cannot be loaded simultaneously.
Summary: This is a fairly advanced unit for the price, for example, compared to the comparably-priced Garmin series. It can now he had for less then $299. PROS: the touch screen interface, all of US maps preloaded, and generally good directions, user interface and options. I particularly like the GPS diagnostics screen where you can see which satellites are being tracked (I am a GPS geek).
Summary: Overall, I think this was an excellent product for the price. There are a few quirks. (1)The windshield adapter broke after only two weeks of use. I am unsure how to replace it. (2) The device sometimes fails to give local street names for routes. It took me a while to figure out how to type in the route number so it could find it (type in "RT 2" and not "ROUTE 2"). Overall - this product is great...for the price. (Hey...it's cheaper now then when I bought it!!!
Summary: This GPS gets the basics done, and belive me I am glad to have it if I get lost, but it does lack on its mapping and finding a location/business. I know for instance when searching for a Walmart when one was close by, it wasn't able to locate it or direct me to it, and it was not a recent build, it was a location that has been around for over a decade.
Summary: If you are looking for a cheap GPS. This unit does the Job. The User Interface is a bit clunky and it's slow, but it does work. The unit is not smart enough to figure out what you are trying to enter regarding streets that have several names. This is a decent entry level GPS. I returned it and went with the Garmin Nuvi 360 since I had the extra $$$ and it's Absolutely AWESOME.
