Seems like you'll have to lift up the cup holder/usb compartment to take the coin out. I am guessing you'll have to follow a few steps from this page http://www.ct200hforum.com/forum/lex...l-armrest.html
Although meant for a different project, you should be able to reach your coin by following the steps up to lifting the cup holder compartment. If you don't feel comfortable doing this, just take it to the dealer. However, that will make this an expensive dime.
