I just created an account to post on here and am looking for a little bit of advice.
My father purchased a new truck (Well, new to him anyways) and it has a Pioneer AVIC-Z140BH in it, but whenever he tries to do anything, it just says "No Applicable Program".
From what I've read so far, it sounds like someone tried to install this "Hackmode" on it.
I have already downloaded the "supertestmode" file from a different thread on this forum, and have downloaded two firmware files from the Pioneer website that say they're firmware updates, but on the 4.600 version it states:
"This firmware update applies only to AVIC-Z140BH or AVIC-X940BT units sold in the United States and Canada, and where the software has never been upgraded."
and on the 5.100 it states:
"This firmware update applies only to AVIC-Z140BH or AVIC-X940BT units sold in the United States and Canada that have been upgraded using the NAVTEQ softtware upgrade T1000-20495."
Is there any way to tell in testmode which version is on it already?
Is there a way to revert back to the factory default firmware?
Any other tips or words of wisdom are appreciated, since I know next to nothing about any of this.
