Only suggestion I can give you is to try disconnecting the negative battery cable and let it sit a couple of minutes before reconnecting it. It "may" get the head unit to reset and start working properly, if you're lucky. If not, the head unit would have to be removed and sent out for repair or replaced. Bose Corp. does repair this units, but, it will probably be cheaper by a third party site. If you Google "Nissan Bose radio repair," you should get several hits of companies that offer repair services.
