Not to my knowledge. There's an fm remote for the Sony recorder MZ-G750 for example that won't actually play radio for any Sony portable OTHER THAN the G750. Remotes that CAN work with the 505, however are: RM-MC11EL (LCD backlit remote) RM-RM-MC10L (LCD non-backlit remote - comes with Euro N707's) RM-MZ4R (Non-LCD remote) There may be others.....but non-Sony remotes that work with the N505? ...doubtful.

what KJ_Palmer is talking about is called the "memory effect." it happens. well, at least the short battery life part.
