Onboard electronic device operating unit

An onboard electronic device operating unit comprising:

• a plurality of setup operation sections capable of changing setting states of control contents for an onboard electronic device;
• a current setting state acquisition means for acquiring a current setting state of the control contents;
• a needle-type display apparatus having a dial, a needle rotatably provided over the dial, and a needle driving motor for performing incremental rotation of the needle, wherein the dial has a scale so as to be capable of directly reading the current setting state of a predetermined control content for needle display out of the control contents;
• a needle calibration section for calibrating a start position for the incremental rotation of the needle over the dial in units of the scale;
• a mode change operation section for changing between a normal control mode and a needle calibration mode as an operation control mode for the needle, the normal control mode controlling the needle driving motor so as to move the needle over the dial in accordance with the acquired current setting state of the control content for needle display, the needle calibration mode controlling the needle driving motor so as to move the needle over the dial in accordance with an operation on the needle calibration section;
• a mode setup means for setting the operation control mode based on an operation state of the mode change operation section;
• and
• a needle operation control means for controlling the needle driving motor in accordance with the operation control mode so as to move the needle over the dial.
