Getting radio piped through would be relatively easy Robbie once Bluetooth link established from your smart phone. Some have built in FM tuners with headphone lead as aerial. Then you have Internet radio apps although reception via mobile data may be an issue. Finally you have stand alone Bluetooth capable radio modules.
I'm all for adopting latest protocols with in-car entertainment but MMC seem to have latched onto this path whilst stripping the charged for option on Plus Four to a bare minimum, more basic than that offered on Classics.
