how do you sync ical to a 2006 apple ipod???

Howdy hmbuchmannfma,

Thanks for using the Apple Support Communities.

I see from your post that you want to export your calendars from iCal on your Mac to your iPod. For assistance with this, please follow the steps outlined below.

Export your calendars

1. Open Calendar.
2. If your calendars list if not visible, click Calendars in the upper-left hand corner.
3. Select the calendar you want to view from your iPod.
4. Select File > Export > Export …
5. Save the file to your desktop. This creates a .ics file.
6. Repeat until you have created a file for each calendar you want on the iPod.
7. Connect your iPod to your computer using a USB cable.
8. In iTunes, put your iPod into Disk Mode.
9. Open your iPod in the Finder. It should appear in the sidebar of a new Finder window under devices.
10. Open the Calendars folder on the iPod.
11. Drag the .ics file or files into the Calendars folder.
12. After the transfer finishes, eject the iPod.

After you copy the content to your iPod, go to the Extras menu on your device to view your contacts or calendars. If you want to update the contacts or calendars on the iPod again, repeat the steps above.

Contacts and Calendars are not supported on the iPod nano 6th and 7th generations.

Export contact and calendar data to your iPod using iTunes for OS X - Apple Support

Take care.
