Buick Rendezvous Driver Information Center

Ok.. I just purchased a Buick Rendezvous and was excited about changing the programming of the DIC to my personal needs. There's just a small problem... I inadvertently switched the language to French and now I cant seem to get it back to English, I have tried everything and it is driving me crazy...... HELP!!! does anyone know what I did and how I can get back to English....

Just a guess, try reading the manual and you could probably figure it out....
