I looked through the entire site and can't find any info on my particular problem. When I try to update my Z2 with method 2 posted by hyperite everything goes well until its asks me for a password to continue with update? I did the 2-wire grounding and that is working fine. I inserted the update disc and I press Map. The unit reads the CD and then asks me to update? I click YES and then while reading the CD for about 1 min, the unit asks me for a "Pioneer Password" to continue with update, it give me a YES, No, Cancel button. I clicked on yes and it asks for a long password, then i tried the No, then it shows me a DeviceID no and a back button, then tried the cancel and just kicks me out. What is the password to update the unit to allow my to bypass my Z2 using method 2. No one has posted this problem and I was wondering if anyone knows how to fix this? Is my HDD locked and doesn't allow for updates? If anyone has a possible solution, please let me know!!! Thanks to anyone who can help
