To get around the password,
Download the official firmware from Pioneer, Download AVIC-Z120BT Firmware Update Version 2.003
Then download the firmware hack, AVICZ110BT-2.004.zip (25.75K)
Extract both .ZIP files. You will now have one folder called " AVICZ110 " this is the official update, and you will have two files " EU090APL.VER " and " RenewalIFLib.dll ".
Cut the " EU090APL.VER " file and past into the " AVICZ110 " folder replacing the original file. Now cut the " RenewalIFLib.dll " and paste into " AVICZ110/APL " folder, again replacing the original file.

To update maps,
