I just replaced my second in-line remote, M9128G/A, apparently no longer available, with the iPod Radio Remote, for use on my iPod Photo. It functions correctly controlling playback, but does not give me FM radio access. The Radio option does not appear on the Music menu. The iPod is running version 1.2.1. The manual states that the iPod should be running 1.1 or higher. The playback functionality is more important to me, given my use of the iPod, but I'd like to use the radio if it's available on my iPod. Is it available on a 4G iPod? Has anyone successfully used this feature on an older iPod? Pleas advise if I'm missing something. Thanks. JoeJazz
