I need to gather some more information from you in order to help.
You say that this is a GPS made by 'Smart Way'? I am not familiar with that brand. Could it be a Garmin, or a Magellan or a TomTom?
Is it a hand held unit or one for the car?
Let me know and we can continue.
There is a 'SmartGPS' manufactured by Magellan which is one of the three brands I mentioned. Is that waht you have? A Magellan?
