I have a 2006 Saturn Relay with a 40Gb DMS which stopped working about 3 years ago. I've tried hacking the DMS, re-installing the firmware, and even trying to hack the vehicle. The display will show "system loading" until I stop it, I've waited up to 45 minutes. Anyone know anything about the GM system or would be willing to work on it? Any and all suggestions would be great. Thanks.
