Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your WOSTOKE Car Android Navigation Stereo. This unit is designed for Subaru Forester models from 2007 to 2013. Please read this manual thoroughly before installation and use to ensure proper functionality and to prevent damage.

Important Notes
CANBUS Requirement:
If your car has an original amplifier, a CANBUS adapter must be purchased separately. Without the CANBUS, the unit will produce no sound. Typically, if your car has a large colorful screen or factory navigation, it indicates the presence of an amplifier.
For CarPlay or Android Auto functionality, ensure you select the correct product options, as this specific model does not include built-in CarPlay or Android Auto.
