Cobra Nav One 4500 Portable GPS system

I have a Cobra Nav One 4500 GPS system that is not working properly. It was working properly last year, but now it doesn't seem to know where it is, its not finding the satellite. Does this ubit need to be upgraded each year ? What do I need to do to get it working again ?

Of course you have already got it in a good place that is known to get good reception. It has a clear view of the sky. If all this is true.
I would take that unit to a good local shop that repairs GPS/Fishfinder/offshore depth combo units for fishermen. There are some good repair guys in those places. If they can't help you I would send it to the factory. Here's the address.
