Throw it away or take it back if you want to use it with your phone, they need to do something with the volume for the phone. Also it is just not a good GPS unit. That might be why it sold for $149.00... They had to get rid of them to dummies like me....
We'd be happy to work with you in an attempt to resolve your concerns with your GPS navigator. If you'll reply with the model number (we presume it's the NS-CNV20, but it's good to be sure) and more specific details about the problems you're having, we'll do our best to present you with some options or tips for troubleshooting.
