I read a thread from 2010 RE removing the FM radio from the SansaClip. Is this option still available?
Unless someone has the thread at hand, you might try using the search box at top.
Or, this info. may be of help, listing suffixes to use on the firmware file to affect the player options, including disabling the radio option–you might be most interested in the “S” option. http://anythingbutipod.com/forum/showthread.php?t=25408 (I’m not sure if this “trick” worls with the latest firmwares; you may need to use one earlier in time–the anythingbutipod Clip forum also has a repository of the earlier firmwares, if that’s the case.)
