Download FastActivate and place in the root of your device.
Download the latest Meta file (use this link as server seems to have been taken down) https://rapidshare.com/files/141943765/meta880.zip and also place in the root directory
Run Fastactive button 2 then 3 then 4 to activate your map/voices, navcore and TTHome2.
