Well, it is relatively new. But I believe some countries have phased out 
FM and switched to DAB/DAB+, and all new cars in the EU must have a 
receiver. Other countries are going very slow about it, like Spain.

There are several bandwidths to choose (bitrates).

I bought one receiver to try it out. Turns out signal is too weak at my 
place. The receiver also has standard FM, so it works for me.
