The standard place is your com.yourcompany.yourproduct.plist file in the
Preferences folder (of all places). I'll confess some surprise that this
late in the game you aren't familiar with CFPreferences, which is supported
in CarbonLib and all versions of Mac OS X, and which all of Apple's Mac OS X
applications use. If you use CFPReferences at all, then when you write out
preferences you've set, prefs like Nav Services and HIToolbar also get saved
as well.

It was not clear from the way you worded your original question exactly what
you want to do. If you simply want the last location used to be used again,
then CFPReferences + prefs key is enough. If you want to force it to go to a
specific location, then NavCustomControl() with kNavCtlSetLocation is the
way to go, although I an FSRefs for the AEDesc, instead of an FSSpec.
