How do I connect the location of a calendar event with the iPad maps app? I would like to be able to either navigate from a calendar event to its location within maps, or view all upcoming events on a map. Preferably, both.

Sadly, (as of iOS 4), this cannot be done. The location field of an event does not recognise an address, no matter how perfectly you enter it.

[UPDATE] In iOS 5, the location field in any calendar event will (if properly formatted) hyperlink to the Maps app.
