Check the switched ignition wire. The screen uses the ignition feed to know when to sleep. If that wire is connected to a permanent source by mistake, the screen never receives the signal to shut down.
This is worth fixing the same day. A screen left awake on a parked car will flatten the battery.
Check in order:
- Measure the ignition wire at the connector with the key off. It must read zero.
- Confirm the ignition feed is a true switched source, not an accessory circuit that stays live.
- Confirm the permanent and ignition wires are not swapped.
- Door input. On an Elite X install, the door input can wake the screen. Confirm it is not being held active.
⚠️ Do not leave the vehicle parked with the screen awake. Disconnect the permanent feed until the wiring is corrected.
