The RNS-E is electrically plug and play even if you have the ocncert radio now using one a RNS-E adapter similar to the one used with the Symphony II. The issue is that you will need to convert your center console from single DIN to double DIN first. This involves installign a new radio cage and A/C control unit (or modifyng the faceplate of your existing A/C control unit). Not impossible but much more work.
