Displays head up problem - Zebra Z4Mplus Label Printer

It sounds like your NHDT-W55 is having issues with displaying audio and video correctly. This could be caused by a faulty connection between the head unit and the speakers or a faulty wiring connection. To troubleshoot, first check all the connections between the head unit and the speakers to make sure they are securely connected. If the connections are secure, then check the wiring connections to make sure they are not loose or frayed. If the wiring connections are good, then the problem could be with the head unit itself and you may need to contact a professional for further help.

In relation to what? If someone tells you "heads up" you should be looking around. If its heads up display on a vehicle it a display that is projected onto the inside od your windshield so you can keep your "head up" and still see your speed, etc.

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This PI was superseded to update Recommendation/Instructions.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).

MiniDV Video Head Cleaning Tape is available in stores.
Thanks.

Problem is video head VEG1731,part name CYLINDER U

Could be because the video head is worn, however, in some LG/NEC VCR's from a few years ago had a problem with the video head plug not fitting into it's socket correctly... So try disconnecting, and reconnecting the vid head... Does the picture look OK before the message appears? You need to make sure you remove any dirt inside the 3-4mm holes on the side of the head cylinder, just be careful not to copper windings inside.

Probably a burnt light bulb

Look for "TITLE" button on the right hand side of the display.
press TITLE repeatedly until the time is displayed.
set time.
when power is OFF but iginition is ON press TITLE to display the time.
i hope this solution helps .
