Recording on IPOD from radio

Does anyone know if there are devices for docking an IPOD to record
from FM radio. I’ve seen them for voice recording or for recording a
current media, but I want to record from the radio.

Nope, nothing so far. The lack of FM recording built-in as well as 3rd party support is one of the biggest gripes against the iPod. It’s one reason many people hate them.
