ok, so after reading through this thread, it seems like you can use the 'HACKMODE' to upgrade the z120bt to z130bt?
Here is my question:
I upgraded my z110 unit to the z120 software. If I were to want to upgrade to z130 from where I am now, would I just use the Condi HACKMODE: download all 3 versions of the file and 'upgrade' it accordingly, then just plug it into my unit & go through the motions?
