Your car isn't worth any more than it was before Nissan got rid of the MT Sport/Touring package. Most people don't care. There will be some people out there that may be willing to pay more if you can find them. But the fact is the OEM nav is terrible and no one wants it. You can take care of all the touring package elements with options from Nissan or better aftermarket parts.
