Hi Guys,
I would really appreciate your help if you can let me know how to unlock AVIC Z2. I have recently got it installed in my car. I did download the .ISO file and burned it as a image CD; but when I insert the CD and hit the map key it say the update has already been installed, so basically does nothing after prompting this message. I have also grounded the wire as instructed in http://avic411.com/forum/viewtopic.php?t=8783.
Does any now why it would do this and if some can give me recommendations?
Thanks for your help in advance.
