Answer
Sorry, but specific questions about particular models of cars and/or audio systems for them is impossible for any "expert" to answer, as I don't own the car nor the audio equipment.  Research on the Web using search engines or call your auto dealer for assistance.  Wouldn't want to fry something serious in your car/truck with bad advice, like the computer!  Cheers, Wink
