Compatibility Notes:

Vehicle Specific Notes:

  • 2009 Pontiac G6 - GM changed the radio halfway through the year so there are two harness possibilities in this vehicle. If the radio in the vehicle looks like the first picture you are good to use the OS-311b. However if the radio in the vehicle looks like the second picture you will need to use OS-311.
