Dec 26, 2009 gps navigation, hacks, sprint
You’ve got OnStar enabled GM vehicle and don’t use it? How about we told you that you could hack into to GM’s controller area network – which they call GMLAN – and make use of the GPS data?
Yeah we know – a simple USB GPS receiver is cheap and is easy to use; but who wants to do that when you can pull your car apart and access what’s already yours? See this as a way you sticking it to the man!
sprintf(nmea,”%u,N,%03u%02u.”,latminsint,longdeg,longminchar);
printf(“%s”,nmea);
for(k=0;k<8;k++)
{
checksum = checksum ^ nmea[k];
} //end for
If any part of this makes any sense to you follow this link to hackaday and get started!
