From post #140

Thank you! I read that just after I posted. 

This seems more complicated than it is because there are two different AVIC series that use this upgrade: Z-series (Z110/120/130/140) and X-series (x920/930/940). Each series has its own forum. Most of us have been reading both forums ( plus the F-series one) since the knowledge needed is spread out and it is a common solution. To complicate it even more, there are two different sets of files for the US/CAN 2015 upgrade. One set only works with the older units (Z110, Z120, x920) and the other works with newer units (z130, z140, x930, x940).

 

With previous upgrades (normally released annually) we only needed one set of files (UPDATE, FIRMWARE directories) and only needed to place on the SD the CardInfo.CIF file for the older or newer units. For some reason that didn't work this year. Many of the UPDATE files differ between the older and newer units. I still don't understand why.

 

Keep in mind that you are reading a thread in the Hacks sub-forum forum which is a work-in-progress - not a how-to procedure. It presumes a certain level of expertise. However it seems that the messy details have finally been sorted-out. We now have a very simple process which only requires a little knowledge on using your computer - basically how to download, extract the compressed files, and copy them onto your installation SD.

 

Unfortunately links to files sometimes get stale. They all do eventually. For the time being, get your files here:

• z110bt, z120bt, x920Bt - older units
• z130bt, z140bh, x930bt, x940bt - newer units

Then extract the files, copy UPDATE, FIRMWARE, and CardInfo.CIF to the root of a freshly formatted FAT32 SD, and insert it into your unit.

 

This works perfectly. Thank you to everyone involved!
