Yes, it is very difficult to name the radio stations especially "0, 1, 2, -9". So, I give up to name the radio stations. I use M-Crew for CMT-M333NT to name the radio stations in Computer. And I can use editor to edit " FM_Preset.INF " radio's frequency and name. It is very easy. But, it is only uploaded frequency into CMT-M333NT. I don't know it is M-Crew's bug or Japanese version problem.
