What is the method for navigation system upgrade?
1 Answers
Generally, the officially provided free navigation software upgrades are divided into two types: one is universal machine software, and the other is brand-specific dedicated software. Copy the downloaded files to the root directory of the USB drive. Before copying, you must empty and format the contents of the USB drive. Press and hold both the MENU and NAV buttons simultaneously for 5 seconds. The central control system will pop up the system upgrade interface, then select software upgrade, and click on main control upgrade.
