ok guys.. i just received the update SD cards today and finished updating my unit
Let me give you a quick tutorial on how to do it (just in case)
Go to the settings of the Z110 and write down your device number
Then you have to get the password for the update. You can do it here
https://www.pioneernavigationupdate.com/navigationupdate/
enter the media code included in the package along with the device number of your unit
WRITE DOWN YOUR PASSWORD IN A SAFE PLACE, YOU CAN ONLY GET IT ONCE
The main update takes 23 minutes
turn on your radio, let it boot up completely, insert SD card #1
it will ask you to do the update, enter your password you got from the website
wait 23 minutes... and VOILA! You have a Z120
keep the SD card inside the unit. It includes a bluetooth firmware update from 2.50 to 3.10
after rebooting, go to the bluetooth settings and do a firmware update. It takes approx 5 minutes
after bt update is down, power off vehicle
turn vehicle back on
take SD card #1 out and insert SD card #2
go to the bluetooth settings again and perform another firmware upgrade. This time from 3.10 to 3.11
wait 5 minutes or so and you are done.
ENJOY
