MY 2011 radio/cd/aux quit working w/trouble codes 2 &3. Will a radio/cd/aux from an 2009 LT work in my 2011 LT? If any member has an interchangeable working unit for sale, LMK how much. I figure about $15 shipping included in price.There are several on ebay from 2009s n 2010s, but not from 2011 as of last search. Thnx! Shipping would be to Kansas City, MO. 64030. Email/phone on request, if needed. Thanx!
