To fix a blank home screen issue on your DigiTech QM4000 after connecting to Maps, press and hold your finger on the top of the screen and slide down to pull down the status bar. This may help access volume or system controls that could resolve display issues. If the issue persists, try disconnecting and reconnecting the device or restarting the monitor.
