I put it in last week. For $230 you get an 8 CD changer as compared to a 6. They give you an adapter that just plugs right into the prewired plug in the trunk. It rocks. I can't understand why anyone would do it any other way. The only downside is that the changer you get from your dealer is guaranteed for 3 yrs/50,000 miles. Panasonic only gives you 1 yr. For a $230 item that will most likely never break anyway, who cares?
