For what it's worth, I now own both a R2500 (Japanese version with no P25) and a PCR2500 (US version cell blocked with P25). Today I finally got around to trying the R2500's remote head on the PCR2500.
Despite Icom's claim that it won't work due to "key internal differences", I can confirm it works fine. Why Icom wouldn't offer the remote head as an option to add to the PCR2500 is beyond me.
