【Car Radio Model】For Chevy Silverado 1500/2500/3500HD (2007-2013) (2nd Generation); For Tahoe (2007-2014) (2nd Generation); For Suburban (2007-2012) (10th Generation); For Avalanche (2007-2013); For Express Van (2008-2019); For Chevy Impala (2006-2013); For GMC Sierra (2007-2013); For GMC Savana (2008-2019); For GMC Yukon (2007-2014); For GMC Acadia (2007-2012); For Buick Enclave (2008-2012) If you are unsure of compatibility, please provide a picture of your car's dashboard to confirm it. 【Bluetooth Car Stereo】Implements single-channel Bluetooth 5.0 architecture with functional limitations: Bluetooth media streaming becomes disabled during active CarPlay/Android Auto sessions. Hands-free telephony and CarPlay-native audio streaming remain operational through primary USB/Wi-Fi connections. 【Online Navigation Integration】Unit incorporates GPS navigation through web-based mapping applications. Full functionality (real-time traffic visualization, speed limit notifications, restricted zone avoidance) requires permanent GPS antenna installation and continuous cellular data connectivity via paired mobile device hotspot. 【FM/AM RDS Function】Analog radio functionality displays station frequencies exclusively (e.g. FM88.8). Digital radio metadata display (station ID, program info) necessitates supplementary DAB+ module acquisition with USB interface capability for digital signal processing. 【Steering Wheel Controls】SWC integration utilizes OEM Canbus architecture through 8-pin AMP connector. Pre-configured plug-and-play operation requires no resistance programming. Native parking sensor systems achieve automatic synchronization with aftermarket reverse cameras. Third-party parking sensor integration is protocol-incompatible. 【CarPlay & Android Auto】Dual-mode wireless/wired smartphone projection operates without external adapters. Android Auto functionality may exhibit device-specific incompatibilities due to manufacturer-imposed OS restrictions. Connectivity failures constitute handset compatibility issues rather than unit defects. 【Reversing Function】This unit excludes back-up camera. If you need a rear camera, please purchase it separately. 【Support Factory OnStar Sound System】Connection way: Please make sure that the white red plug (marked "AUX L/R OUT') extended from the Canbus connect to the white red plug (marked "AUX L/R OUT) on the 20P RCA cable. And Splice blue wire marked AMP CTRL to 20P AMP wire.
