I believe the CAL is for *calibration*, not calculating. My owner's manual says that the compass in my 2023 Equinox LT operates off of GPS from the antenna on the roof. It says when a GPS signal is lost, the CAL will show on the driver information center. It says get out into an open area where a signal can be re-established. If you've loaded a rooftop carrier that blocks the antenna that could be your problem or anything else that blocks the antenna. If that doesn't work, I guess you've got some other problem.My 2017 Equinox compass is stuck on CAL which is suppose to be calculating. It has calculated in the past with no problem, this time it's stuck.
Has anyone else had this problem and what is the fix? thanks in advanced.
