Hello all, I apologize if you feel I am hijacking this thread but I had found this forum looking for information and some helpful hints as I explore my gmlan system in my truck, adding navigation radio and backup cameras.. Have read this entire thread and I have taken some notes and will be experimenting and hopefully learning as I'm going. Please don't think I will be asking for all the answers, lol.. I heard mention of this GMW3110 document and that it contains quite a bit of information in helping understand the bus and the protocols.. Does anyone have it? or know of a location where it will not cost me an arm and a leg to get?
So far I have the door locks figured out, can activate remote start using the RKE or Onstar commands.. Learning this 29 bit header is confusing, but I am getting the hang of it.. Really want to research 11 bit and see what else I can work with..
thanks, Sorry don't really have a lot to offer, hopefully in the future I can help out.. I am a GM dealer Tech, if someone needs some info I have access to, let me know.. tek1229
