how do I enable the FM receiver on my iPhone 6

nice but it requires hard headphones. Why not allow the use of bluetooth headsets?

Because the bluetooth headphones would not work as antennas as they are not physically connected to the iPhone.

There is simply no way to get FM radio on an iPhone.

There is no mention of a program to dial, but the picture illustrates one running on the phone.

Not sure what that means.

There "IS" a radio FM receiver in iPhone! At least in iPhone 5! But it is disabled for "rights" problems!

That is false.

Once again, that isn't what you said. You didn't specify iPhone. Now that you have I couldn't care less about your comments.

The Samsung Galaxy S7 does.

Who cares what the Samsung Galaxy S7 has or does... if you like it so much, go buy one.

😁 I can find suppliers and sell an FM radio for $2. 😁 I think you miss the point.😁😁😁

I know

That is not at all accurate every mobile phone both android and iPhones are equipped with radio receivers that are not activated
