Bluetooth is a dud on the new Apple iPod Nano 7th generation. :-(

Phones are too heavy to use while running and wired headphones are too restrictive, so the combination of Bluetooth and the Nike+ pedometer support were the ONLY reasons that I bought the new iPod Nano.
First and foremost, I cannot Bluetooth pair the nano to my iPhone, so the only way to sync Nike+ after my runs is to plug the nano into my Mac--which is a Mac Pro (tower), so it can't go with me, when I travel. :-(
Second of all, the FM receiver still requires wired headphones--there is apparently no FM antenna in the nano, itself. So at the gym, I cannot use the nano to tune into a TV audio (relayed via FM), and listen to it wirelessly on my Bluetooth headphones. Even if I plug in the supplied headphones just to act as an FM antenna, I cannot then send the audio to my Bluetooth headset--the BT icon shows that my BT headset is still active, but there is no way to change output devices in the Radio app. Radio app requires wired headphones as an antenna AND will only send the audio out to the wired headphones, despite the presence of BT headphones. :-(
(NOTE: Music app does let me choose output devices between wired vs. BT headphones, so the fact that the Radio app doesn't let me choose BT is a blatant oversight).
Thirdly, sometimes I like to record an idea, while running--can't do it strictly with Bluetooth. The nano's ability to record voice memo's does not work with BT headphones, even though my BT headphones do have a microphone (e.g. suitable for making calls on an iPhone). The Voice recorder requires WIRED headphones with a microphone. To add insult to injury, the supplied headphones do not have a microphone--I had to borrow the headphones that came with my iPhone 5. It is SOOOOO annoying that Apple did not make Voice memo recording work with Bluetooth, and then they didn't even bother to include the headphones with a mic! :-(
Lastly, the taller form factor doesn't lend itself for use as a running watch. They should fix all of the above and go back to the old form factor.
Conclusion: Apple finally added Bluetooth audio to the iPod nano, but it is only useful for music. It cannot be used to relay FM broadcasts, such as from exercise equipment (and there is no antenna in the nano itself), so wired headphones would at least need to plugged in for FM relay over BT to work. Finally, BT cannot be used for Voice memo recording. THEREFORE, Bluetooth in the new iPod nano is a dud. :-(
