99 GS400 Navigation Update
Can someone please tell me if 1999 GS400 Navigation is able to update or not? Is there a specific CD? What is the part # for all regions? If I can find them used or whatever, is it simple as plug and play? I-phone does the trick however, it would be nice if Navigation did that for me.
