Recently bought my first car and have found that it has an AVIC-X930BT. No password was provided (I can't even set the address in my GPS, or click on any other settings besides Audio) assuming that means I need to find the password. Well I put test mode on my SD and put it in the unit. When I went to the location where the tutorial says the password should be. I see no "password" folder. Can anyone tell me what I'm missing here.
