Garmin Mobile PC v5.00.70 supports TTS. It uses the Windows native TTS engine and has nothing to do with Garmin TTS voices.
By default there's only "Microsoft Anna - English (United States)" available in Windows Vista and Windows 7. Chinese Windows Vista & 7 versions also includes a Chinese TTS voice. Older Windows XP uses some other variants like "Microsoft Sam". Extra TTS languages has to be installed from 3rd part providers.
