Go to
www.kiatechinfo.com.
Register.
Go to Shop.
Select the Optima [MG] (which is the new body style 2006.5-2007).
Select 2006 (I know you have an 07, but the 06 selection has more info).
Then Engine Type and your engine.
Click on the link on the left hand side and select Body (Interior and Exterior), then Interior then Console, and finally Repair Procedures.
Word of caution, although I have not removed the console, some of the images and directions are "much easier said than done", for lack of a better term I'm saying everything is fit together nice and tight, and doesn't just "come apart" as easily as you would hope.
