The 'approach' available on the Garmin handhelds is limited to just the last leg of the IAP from Final Approach Fix to the runway numbers . . . . and not the full McCoy found on the 530 (which is actually not as detailed as a Jeppesen plate - i guess you need a G1000 for that!)
The usual reason given for this stripped down approach on the handhelds is that Garmin's lawyers don't want to encourage you to use the kit for a full on procedure down to minimums ! (and that's also why the glideslope disappears at 1000' when using vertical navigation on the panel page).
(and thanks CJ . . . . . that's a good tip!)
