7th gen iPod radio with a bluetooth headset in motorcycle helmet I have just bought a 7th generation iPod and I have a bluetooth headset in a motorcycle helmet. Is there any way to listen to the radio through bluetooth given that the headphones are the antenna?
Assuming you are talking about an iPod nano.


  iPod nano uses the headphone cord as an antenna, so you must connect headphones to iPod nano to receive a radio signal. For better reception, make sure the cord isn’t tangled or coiled.
  FM radio will not play through a Bluetooth accessory.
