Released last night, MapSource 6.10.0.2 Beta: (8.73mb)
http://www.garmin.com/support/download_details.jsp?id=1229
Changes made from version 6.9.1 to 6.10.0.2 Beta:
• Fixed problems updating MapSource from within the application after a beta has expired.
• Added support for postal-code based address finding in the U.K.
• Added graphical track editing. To enable track editing, turn on the track edit toolbar by going to 'View > Show Toolbars > Track Edit'.
• Added the ability to select a track's display color. This affects how tracks are displayed in MapSource and compatible units.
• Modified the drawing of interstates and highways so that the line width changes based on the map's zoom level.
• Added support for entering Japanese addresses in Kanji, as well as Kana, in compatible map products.
• 'Portrait' or 'Landscape' layout setting for printing is now remembered.
• More robust communication with Pocket PC units, such as the iQue M3 and M5, is now provided.
• Routes calculated in MapSource will no longer cause driving-direction problems on certain units, such as the Quest.
• Made MapSource compatible with 512 MB Garmin data cards.
I’ve tried the second item listed, it doesn’t seem to be a full postcode search, you still need a street name to get close, give it a try…
