I called GM onstar and you can upgrade for a $600.00 dollars fee to the newer system. The problem I have is paying $55,000.00 dollars for a car with a dated junk system. Shame on GM for being so cheap to the corvette customers. They will never have the customer service skills that Porsche and others have with the high end customers.

Strange....they told me $550 and they pay it if one signs up for a 3 year stint.
