I understand your point, and I think I should have explained myself a little bit better, what I'm looking for to do is, has any body find a way to use your own phone instead of Lexus phone? I don't want to remove the whole kit, just the Lexus hand set.
and using the handset free system, with my cellphone.
I know for sure that its possible, but I thought I could use some other people experience, not to mess with it. I just have to find the right diagram for it, I used to be a phone tech, so I'm kind of familiar with whole concept, I know the wires go to the car's computer, but that can not prevent you of using your own phone, as I said before it is quite possible.
Well I guess I have to take my old phone's tools out once more to figure it out.
