Hey guys, I recently purchased a SC cortex and haven't been able to use it, thanks to an annoying "vehicle response was incorrect..." error message. I've called SC on 3 occasions and was told to unplug my aftermarket sub amp, remove some fuses (radio, stock amp, onstar) and try again. Still got the same message. I called them yet again earlier today and was told to check the voltage on the battery, that it should be at 12.8. Just checked it and it was at 12.3 (vehicle off, on it was where it should be, 14.4ish)
Is this right? Does our battery have to be above 12.8 for the cortex to work?? I know a battery reading around 12.5 volts pretty much indicates a full charge.
And before you ask, yes, I have updated the cortex since I purchased it and just did it 5 minutes ago before trying again.
Any feedback/ideas would be great...
