iPod touch Calendars - removal

[Eski]

Hi folks, we've synced up my sons Google calendar which is fine. But now we want to get rid of the other calendars that are now in the way. On the ipod these are listed under On My iPod touch - we have All on my ipod touch and the then the three from iCal despite not having them synced in itunes.

We just want the single calendar.

Any advice? Thanks.

If you delete all the ones your don't want from iCal on your Mac and then sync the iPod, the ones on the iPod should go away as well.
