Hi Roger, I'm glad to help. Below is the procedure for resetting the compass on your vehicle.
COMPASS VARIATION ADJUSTMENT
Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance setting may need to be changed.
To set the compass variance:
The flashing "C" in the Instrument cluster if for the Compass. Here's the bulletine...
Subject: Compass Displays a Steady or Flashing "C" In Place Of Directional Heading Models: 2008 Saturn VUE built on or after 11/09/2007 This PI was superseded to update Recommendation/Instructions. Please discard PIT4699.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern: The compass displays a steady or flashing "C" in place of directional heading.
To return to a normal heading display, press and hold the cluster stem for approximately 2 Seconds.
The displayed heading is not correct after driving for 30 seconds, use the following "Compass Calibration" routine.
Press cluster stem until the Season Odometer is displayed (Not Trip A or B).
Press and hold cluster Stem until the solid "C" is displayed. To the right of the "C" will be the "Zone". Refer to the variation zone map above for the correct setting. Turn the stem Right to increase, Left to decrease. It will take a few seconds for a change of zone to be updated in the display.
Once the Zone is correct, press the Stem to display the Flashing "C". Do not touch the Stem again until the direction is learned. Drive the vehicle in slow circles in an open area until you see a compass (oc tant) heading replace the flashing C.
Note: Vehicles built prior to 11/09/2007 were not built with a compass.
Recommendation/Instructions: Engineering is aware of this condition and is in the process of root causing. It is known that the Remote Compass Module (RCM), Body Control Module (BCM) and Cluster hardware are not at fault, and these parts should not be replaced.
Reinforce with the PDI technicians that the Compass Zone and calibration is still required as part of PDI.
Hope helps (remember to rate and comment this answer).
I had the same issue.I opened up the TP30 to find that the wires from the compass to the circuit board had corroded and snapped.Trying to source a new compass unit now.Anyone know if they are the same as the new TP32?
The "OC" indicates your compass is "Out of Calibration". Below is the proceedure to recalibrate your compass.
The compass may need calibration if:
After five seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letters CAL must be displayed
in the mirror compass windows. If CAL is not
displayed, push in the COMP button for approximately
eight seconds or until the letters CAL are displayed.
The compass can be calibrated in one of two ways:
Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or
drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.
You need to recalibrate the compass. The procedure is in your owners manual. Here are the basic steps.
First, you will need to verify that your compass zone is set to your current geographic location. Since I do not know where you are located, I cannot tell you the code. They are listed in the manual. (For example, So Cal is zone 5.)
Second, here is the compass calibration adjustment procedure:
Perform this adjustment in an open area free from steel structures and high voltage lines. For optimum calibration, turn off all electrical accessories (heater/air conditioning, wipers, etc.) and make sure all vehicle doors are shut. 1. Start the vehicle. 2. To enter the compass calibration mode, press and hold the button for greater than eight seconds. The display will then show CAL in the display window. 3. Drive the vehicle slowly (less than 3 mph) in circles until CAL indicator turns off. As many as 5 complete circles may be required. 4. The compass is now calibrated.
Hello. First day I use this device, and have found this tips for compass calibration (as I understand, compass calibration depend on satellite signals - so before compass calibration it's better to get good signals from satellites): - keep device at horizontal plane (as from message "hold level"); - turn it slow, but not too very slow. It's better don't turn device, but get device at hands, and turn around himself with it with constant slow speed, and keep horizontal level of device - by this way I have a more accurate calibration, than turn just in hands or on the table. I hope this will help.
