Download the v1.001 update from Pioneer.
Replace \AVICZ110\EU090APL.VER and \AVICZ110\APL\RenewalIFLib.dll with the files included. 
Copy the AVICZ110 folder with the patched files to the root of an SD card. 
Insert the SD to your Z110BT and it should start updating automatically.

You are now running the patched version. When you try to run a map upgrade insert anything for the password. If it's not taking it, try filling the input box with characters (no numbers).
