I have a Z120BT with the 2015 maps.

• Offset 15AEFC did not match the first post data, but I found the pattern at 15B02C.
• Changing offset 15B02C from 02 00 56 E3 to 09 00 56 E3 made the SAFE MODE menu button appear in the settings menu.  Safe mode button appears to retain the setting when the car is switched on/off but neither setting prevents the parking brake warning from appearing on boot up.
• Changing offset 15AEE8 from 01 10 A0 E3 to 00 10 A0 E3 made no difference that I could tell.
• There are many pattern matches for "01 10 A0 E3" so I guessed wildly --  The pattern for Safe Mode was 130 hex offset higher than the original offset referenced in this post.
• 15B018 = 130 hex offset higher than 15AEE8, AND it has the pattern we are looking for... but modifying this offset made no difference that I could perceive either.

Does anyone have any information about how to pursue this further?  I would like to avoid tearing my dash apart to find out what the installers did wrong with the parking brake wiring.  (The deck was installed several years ago for the previous owner, so taking it back to the installer and making them fix it is not an option unless I want to pay).  I don't care about watching videos... ever.  I would just like to have the radio just come on and work without having to acknowledge the parking brake prompt every time.  Yes, perhaps this makes me lazy... or just a quirk.    

I just applied this update to my Z120BT without any problems.  It took almost 30 minutes for the update to install.  When the update was done and the HU rebooted, the SD card was still in the unit and it prompted me again if I wanted to update.  I assumed this was just my dumbness of leaving the card in the HU so I told it no and removed the SD card.  Everything seems perfect so far.  Thanks a ton to anyone and everyone how helped make this available!!  :mrgreen:
