I went ahead and ordered the updated instrument cluster from a car with the same config as mine and am happy to report that it is almost plug and play. I have a couple of issues and still need to do the proxy alignment. (I ordered the fiat software from ebay and will do the proxy alignment and try to do the odometer correction) The biggest issue that I noticed is that I lost access to the blue and me menu. (Bluetooth still works, but I am unable to add another phone)
