Well I was playing around in ResHack with the iGuidance.exe. On dialog 1004 (which is the enter destination) there is a disabled button called Contacts. All I did was diasble the Recent button and enabled the Contacts button.
Those two lines look like this:
But I cannot get iG to read my Outlook contacts so at the moment it's kinda worthless. This is a PowerPC option only (according to the help file). Would be nice if iNav included this in the next version.
CONTROL "Recent", 505, BUTTON, BS_OWNERDRAW | BS_FLAT | WS_CHILD | WS_DISABLED | WS_TABSSTOP, 123, 121, 16, 14
CONTROL "Contacts", 506, BUTTON, BS_OWNERDRAW | BS_FLAT | WS_CHILD | WS_VISIBLE, 0, 119, 89, 16
PS This is from version 2.0.
