i wish i saw this thread sooner... in case if somebody runs into this situation again, most TV tuners have 6 languages built in but they are not accessible, since the setup menu displayed on the screen comes from Nav computer (unless you don't have nav comp and ONLY TV module - in this case you will not even be asking this question)...
If you disconnect your navigation computer from the car, the menu on the screen will be generated by the TV module... one of the screens will be settings for the TV module, where you can find the language entry... voila!!!
