Terrence,
Parts are around $800.00 to over $1000.00 depending on how much the dealer is taking you for???
Labor should only be one hour or so, depending on if the dealer has a minimum charge. Of course, if you are feeling adventuresome, you could try it yourself?? The hardest piece is the one around the NAV screen....
