Zerone_V, I believe you can get some people out there to remove the VIN programming from the series I units so shouldn't be hard to get series II done... I HOPE!!!
Yeah, a couple of us have nutted out the VIN stuff / programming, and have been able to fit different clusters and radios to different models.
HSV cluster in an Omega, Colour LCD and Radio (With Climate control working) in both an SS and an Omega...
All this using cheap ($50) off the shelf EEPROM programmers.
We are also publishing everything that we find, so as anyone can have a go, and hopefully have people push the boundaries as to what can be done with this stuff.
I honestly think the IQ stuff will be a matter of time, however, because of the cost of the gear, its hard to justify at the moment....
We are currently trying to work out how to enable the VGA input on the colour LCD screen, by faking the data sent from the factory SAT-NAV CAN gateway module.
This should give us a low res VGA input, as well as a separate volume controlled sound overlay for in car PC functions using the factory hardware...
There is a LOT that can be done with the GM Slow CAN bus, but the people that have worked this stuff out prefer to keep the information private.
We are hoping to crack
