Re: VY VZ Head Unit Programming
Mostly it'd be the calibration and region settings for the radio (including the vin). I dont think its operating system code as the software patterns dont look right for CPU instructions (no patterns, too many 00s). Probably also saved channels, settings for base, treble, balance, fade etc. Could be things like raw numbers for voltages to drive the tuner for a given FM frequency and voltages to set volume levels on the amplifier IC etc as the knob clicks up or down a volume notch etc. Some of it looks 8 bit, some 16 bit.

Re: VY VZ Head Unit Programming
Anyone worked out where the Security pin code is located??
I have upload 2 bins of the same model headunits

Re: VY VZ Head Unit Programming
here are the areas that are different in both bin files
Re: VY VZ Head Unit Programming
Probably easiest to work with a unit with a known pincode first.
Nothing really stands out there for what would be the pin.

Re: VY VZ Head Unit Programming
Yeah i know Tazzi,
Been looking over the hex and your right, Nothing stands out....
i might make a phone call and get the codes tomorrow.
and work backwards...

Re: VY VZ Head Unit Programming
Code on Blaupunkt units is calculated from radio serial number. The pin is not in the bin. There is a large static lookup table and a bunch of rotations and substitutions starting initially from characters in the serial number by the values in the lookup table, ending up with the pin.

Re: VY VZ Head Unit Programming
I dont think publicly publishing the algo is a good idea, but heres a big hint at the logic from my tool source code. Hopefully it saves you some time investigating from the wrong angle. You would want to investigate this from a code angle, not a stored in the prom angle.
@commodorenut, if you just want the code for your radio send me a PM.
