For a CHIGEE Display with a three-wire power harness, red supplies constant battery power, black connects to battery negative, and yellow detects the ignition state. Use your model’s supplied harness and fuse.
Connect the three-wire harness
Wire | Connection | Purpose |
Red | Battery positive through the supplied fused cable | Main power remains available after ignition off. |
Black | Battery negative | Return connection for the power supply. |
Yellow | A verified ignition-switched ACC source | Ignition detection; this is not the main power supply. |
Follow your model’s manual when working at the battery. The AIO-6 LTE original fuse is 3 A; do not apply this value to every CHIGEE model or to a third-party controller’s electronic current limit.
Use the ACC testing guide to identify a suitable source before connecting the yellow wire.
Check the installation
With ignition on, confirm the display starts.
Switch the ignition off. The yellow ACC signal should turn off while the red main supply remains connected.
Check that the display follows its normal shutdown behavior. Supported parking or LTE functions also depend on the model, settings, battery voltage and network.
Secure the wiring only after testing. Keep cables away from heat and moving parts.
If the display shuts off instantly, check the red main supply as well as the yellow ACC signal. See shutdown countdown and ride statistics.
Other power connections
AIO-5 Play for BMW uses its compatible BMW navigation cradle. AIO-6 quick-release installations must follow the instructions for the specific module. These arrangements are different from a direct three-wire installation.
An ETC accessory circuit, a vehicle USB outlet and the display’s USB port are not interchangeable power inputs. Check the intended input and the model’s manual; a shared voltage rating alone does not confirm a suitable installation.
For bench testing, see USB power testing. For an accessory controller, see third-party power managers.
FAQs
Does the CHIGEE Display have a battery?
No. It has no rechargeable internal battery and needs external power through the appropriate harness, cradle or supported test connection.
What does the battery icon in CarPlay or Android Auto show?
It shows your phone’s battery level, not a battery inside the CHIGEE Display.
Can I connect yellow to constant battery power?
No. Yellow must detect ignition on and off. Connecting it to constant power can keep the display awake and increase battery use.
