The Axxess Auto-Dectect System is the revolutionary new way to install aftermarket radios in vehicles that require a data interface (LAN or CANBUS). Each interface auto detects the vehicle it is in and automatically configures itself to work perfectly with that vehicle. Then just plug in one of Axxesses new harnesses and you're done. It's that easy. The Axxess AX-ADBOX2 comes with the ASWC steering wheel control harness and allows for a direct plug-and-play with no wire splicing needed for the Axxess ASWC Module (ASWC module required and Sold Separately). The ADBOX2 also retains features like: Onstar/OE Bluetooth (GM), SYNC in Non-NAV Ford, Blind Spot Detection Systems in select Chrysler /Dodge/Jeep and NAV Outputs (Parking Brake Reverse Mute And V.S.S.). It can also be used in amplified or non-amplified systems.
