Can you send us the VIN number so we can look.

No Harmon Kardon but you must remove the CD changer and mobile phone control module.

Parts needed.
----------------
- Headunit wiring adapter
- Microphone extension cable.
- voice control stalk.

Procedure
------------
Ignore all of the optical wiring. Secure so it doesnt rattle.

Extend a cable to the rear left passenger seat and junction with the microphone wires that go overhead.


With these processes you should be able to restore phone function, GPS, Voice control.

Please note that K12 is installed.

thank you for the information. what is k12? anything related to electric voltage? what should i do about it?

If the diagnostic asks, do you have K12 installed. Click yes.
