Folks, I'm looking to upgrade from an RNS315 to a 510 in a 2013 CC. The 315 has DAB and Bluetooth, but can anyone confirm whether the Bluetooth is built in to the unit in 2013 and therefore I'd have to fit a Bluetooth module along with the 510?
If I do, what way does the wiring work? Will a normal retrofit loom work as there'd already be a mic installed?
