Elevate your GM infotainment with Road Top

The Road Top Wireless CarPlay and Android Auto Retrofit Kit is a smart interface upgrade designed for GM vehicles equipped with the HMI 2.0 system. It is a decoder box that links your existing display and controls to modern smartphone features without replacing the screen.

What you get

  • Wireless CarPlay and Android Auto so navigation, music, calls, and messages reach your dash without cables.
  • Navigation and voice control via Siri or Google Assistant, plus smooth switching between OEM and CarPlay modes.
  • OEM-style integration: keeps steering wheel buttons, control knob, and factory interfaces fully functional.
  • Camera and multimedia expansion: supports factory and aftermarket backup cameras, 360-degree setups, and DVR inputs when available.
  • MirrorLink for iPhone and Android, enabling screen mirroring where supported.

How it fits your vehicle

  • Compatibility covers Cadillac ATS, CTS, SRX, XTS; Buick LaCrosse, Regal; Chevrolet Corvette, Impala, Silverado, Suburban, Tahoe; GMC Sierra, among other GM HMI 2.0 vehicles from 2014–2020.
  • Not a screen replacement—the kit plugs into the existing infotainment hardware and remains fully OEM-integrated.

Installation involves some dashboard access and wiring. Step-by-step guidance is provided, and extended after-sales support helps with wiring questions or troubleshooting. Results depend on the vehicle’s configuration and hardware.

Real-world scenarios

Imagine clearer navigation prompts, hands-free calls, and music streaming displayed on the familiar GM screen. Backing up with confidence becomes easier with the integrated camera view, while reversing or parking can benefit from a broader camera setup and mirrors.

By design, the Road Top kit emphasizes a balance between modern connectivity and OEM familiarity. It presents a range of possibilities for users who want upgraded infotainment without a new head unit.

Quality and support matter. Road Top provides installation guidance, wiring assistance, and after-sales support to help with troubleshooting and updates, so you can enjoy the upgrade with confidence.
