I have a 2005 corvette with a "digital ready" onstar box. It appears to be compatible since I don't see a red connector. Instead, there are 2 white and 2 black connectors labeled J1-J4. Is this unit compatible with the 2010 bluestar? Thanks for your help!

To verify compatability, look at the RED connector on the old onstar box. If it has a green wire in pin A3, then your vehicle's radio is probably controlled by the Entertainment and Control bus, (E&C) NOT CLASS2. Even though the rest of the vehicle is CLASS2 controlled, the radio is not. Unfortunately, the BlueSTAR does not support E&C control.
Please email me with any questions.
