Hi Michaelt76.
The 47LM660S is an Italian release and is definitely compatible with the AN-MR300. The AN-MR500 should not work with 2012/2013 models. The 2013 models are/were compatible with the AN-MR400 and the AN-MR300 was compatible with the 2012 models. The AN-MR500 is strictly for 2014 models so the 47LM660S is not compatible with it...IFV
