I recently updated the firmware on my AVIC5000-NEX. The next morning, my car battery was dead with no apparent reason as to why(lights were not switched on, etc). When I remediated the battery issue, my stereo was asking for a password. I didn't install the radio(paid an installer) and I've never seen any password section of the interface, so I'm not sure where the password came from. Regardless, I tried all combinations of passwords I would have set if I set it and forgot it to no avail. Upon contacting Pioneer, I was told the only option was to send it in to have the password reset and
