Issue
The touchscreen system has System Reset feature that can be performed if the function of a SYNC feature is lost. This reset is intended to
restore functionality and will not erase any information previously stored in the system (such as paired devices, phonebook, call history, text
messages, or user settings). To perform a System Reset, press and hold the Seek Up (>>) button while pressing and holding the Radio Power
button. After approximately 5 seconds the screen will go black. Allow 1-2 minutes for the system reset to complete. You may then resume
