If there is then you should be able to add one in somehow but as far as I know you cant.
Welp, there ya go then, I have no clue. I guess an aftermarket radio is your only option. I have an 06 gt with the monsoon n when I bought it there was a different radio put in. Thats what id do then, just get the steering wheel interface n the onstar adapter harness if ya want the chimes. Theyre a little expensive but ebay is the best bet. Ik I wanted my steering wheel controls still n the metra axxess kit works good n is around $50 or so on there.
