RP5-GM52-HAR%20300dpi_1in.pngIf you own a late model GM truck (GMC Sierra or Chevy Silverado) with a 7-inch display and think it’s impossible to change out the existing radio, then you’re in for a treat.  PAC just released the RP5-GM52-HAR harness and when combined with the RadioPRO RP5-GM51, lets you upgrade to an aftermarket radio with ease.  Plus, the combo parts keep all the important features of the vehicle including OnStar, steering wheel controls, front and rear park assist, and more.  So if you’re one who can’t stand the factory radio in your 2014+ GM truck and is ready to jump into the latest technologies found only in an aftermarket radio, make sure to use these PAC pieces.
