It is not interchangeable with GM1A-RST, GM3A-RSTX or GM6A-RST: OnStar, GM LAN generation, connector architecture, Bose equipment and other retained features change the correct interface.\u003c\/p\u003e\u003ch2\u003eManufacturer Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e PAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e GM1A-RS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct family:\u003c\/strong\u003e RadioPRO Advanced\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e GM radio replacement interface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent PAC price:\u003c\/strong\u003e $349.00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetained functions:\u003c\/strong\u003e Chimes, supported factory amplifier and steering-wheel controls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle coverage:\u003c\/strong\u003e Select General Motors applications; verify exact current PAC application before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e do not choose this part from GM make\/year alone.
