Unit Displays a Blank Screen with Only the Clock
The navigation unit will need a hard reset.
Remove the positive and negative battery cables from your battery, touch them together, and then reconnect them to the battery.
This will resolve several potential issues with the navigation system.
If this does not fix the issue, there may be a possible hardware/software related issue that may need to be addressed. Please reach out to support at https://desk.zoho.com/portal/infotainment/newticket or further assistance.
