Pre LCI PDC was an individual module in the back. Post LCI (your 2011) had PDC built into the junction box up front. You just need a LCI/PDC junction box (around $50 used). And extend the wires to the glove box area. I think the issue is the newer CIC iDrive and backup camera don't work with the older PDC. I had to retrofit the LCI PDC to get my retrofitted LCI backup camera to turn on with a retrofitted CIC.
