caesar44 Posted October 5, 2008 Report Share Posted October 5, 2008 I know that when inserting the update disc that it asks you for a registration code. But since the unit is not linked to the internet, why wouldn't it work to just get the registration code for a particular update disc and upload it with its individual code? *using a fake registration with pioneer when getting its code should keep anyone from getting into trouble* Why wouldn't this work?

djmixmac Posted October 5, 2008 Report Share Posted October 5, 2008 Typically software requests a serial number only during installation. The installation software applies an algebraic expression to the key entered to validate the key. As an example, the algorithm may define that a key entered must contain 5 numbers that have a checksum of 25, and that the key must also contain 3 letters that, when mapped into their numerical equivalents, have a sum of 42. A keygen could be created if someone had the time and resources. In order to write a keygen, the author typically uses a disassembler to look at the raw assembly code of the program they are writing the keygen for, checking either the software itself or the installer. Once they have access to the program's code, they can locate the subroutine(s) responsible for verifying that the key entered is valid. Using this knowledge, they can reverse engineer the algorithm used to generate valid keys, which is then incorporated into the keygen Quote Link to post Share on other sites
garrettoomey Posted October 5, 2008 Report Share Posted October 5, 2008 The short version: You have to go on the internet to register the CD with your AVIC Z's Serial number. The registration code it tied to your serial number. the same cd COULD be used more than once, but you would need a unique registration number for each unit. https://www.pioneernavigationupdate.com ... ionupdate/ I would be interested to know if the users that bought the disc last year, and saved their registration code, would work on the new disc this year? New keygen or same one... DJ, Nice write up... Quote Link to post Share on other sites
caesar44 Posted October 5, 2008 Author Report Share Posted October 5, 2008 I was unaware that the registration code was in some way linked to the serial number of each individual z1. I just thought that each disc had a registration code to "unlock" that disc. I knew that there had to be more to it because i was sure someone would have thought to upload that disk somewhree along with its code. sorry for being "special" Quote Link to post Share on other sites
