I know someone probably already answered this question but I havent found the answer. I know that theres a way to get the Navi voice from a 2002 TL to actually work with an aftermarket HU but how exactly is that done? Please help me, my e-mail is intensefactor@msn.com. I am trying to do this myself but I still need some advice and if possible pictures of the wiring diagram that is used to get the aftermarker HU to work with the Navi. Thanks in advance for any help.
