Keep your factory look and controls

This Restyle kit lets you install an oversized Alpine receiver in your GM while keeping your factory look. The package contains a dash kit that's been specially designed to make the big Alpine 8" screen look right at home in your GM pickup, along with wiring adapters that connect the Alpine receiver.

Plug it in and go

Once you hard-wire the foot brake wire and the steering wheel remote input wire, the included wiring harness covers the rest of connections by plugging directly from the Alpine receiver into your vehicle's factory wiring harness. This Restyle package works with GM's regular audio systems, but it is not compatible with the factory Bose® audio system. It allows you to keep all your OnStar functionality, the factory aux input, Retained Accessory Power (RAP), and the safety warning chimes. The package also lets you retain your steering wheel audio controls. Warranty: 1 year.

Compatibility note: This Restyle package is not compatible with GM trucks with the factory Bose audio system.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Features

Perfect F.I.T. Installation Packages: The Alpine in-dash navigation receivers with an 8" LCD touchscreen will not fit a standard Single-DIN or Double-DIN dash opening. To accommodate this large screen in your vehicle's dash, Alpine offers a line of Perfect Factory Integration Technology (F.I.T.) packages specifically for these receivers. Alpine's Perfect F.I.T. installation packages allow the Alpine navigation receiver with 8" LCD touchscreen to fit seamlessly into select vehicle dashes. Perfect F.I.T. is designed to cosmetically match the shape, color and texture of the vehicle's interior. 

Compatibility: The Alpine KTX-GM8K2 Perfect F.I.T. installation package allows seamless integration of the Alpine 8" LCD touchscreen navigation head unit in select 2014-up GM trucks (non-Bose systems only). As always, please consult Crutchfield's Outfit My Car to verify fit and installation accessories for your vehicle.

OEM-Like Appearance: The KTX-GM8K2 Perfect F.I.T. installation package has been specifically fitted and engineered to fit select 2014-up GM trucks perfectly. It comes with a specially formed OEM-grade, high quality/high strength ABS plastic radio housing that is color matched to the dash. This allows the unit to precisely fit not only the vehicle, but also the Alpine 8" LCD touchscreen navigation receiver. In addition, extra care is taken to match the factory dash's shape, texture, and color ensuring a more OEM-like appearance. Unlike traditional universal dash kits, the Alpine Perfect F.I.T. packages include direct fit OEM-like brackets to ensure sturdy support and accurate positioning of the radio in your vehicle's dash.

Retained Factory Features: The included radio replacement interface module (KCX-SRMGM2) allows you to retain factory features such as OnStar, steering wheel control, Aux input, and warning chimes (external chime module included). The interface module also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, parking brake, and foot brake.

Vehicle+Radio Harness: This Perfect F.I.T. Installation Package comes with a GM radio replacement module, radio harness, and vehicle harness for simple installation between the Alpine 8" LCD touchscreen navigation receiver and your 20014-up GM truck. You get all the necessary harnesses and adapters in the box to install the Alpine 8" LCD touchscreen navigation receiver in your 2014-up GM truck.

Note: The vehicle harness contains two Molex connectors which plug into your GM truck's factory radio harness. On the other end of the harness is a 16-pin connector and 14-pin connector which plug into the radio replacement interface module. This same harness also includes to male RCA connectors to retain your factory Aux input and steering wheel remote input wire (green/black) which has to be hardwired at the steering column. The radio harness is fitted with a 16-pin Alpine radio connector and camera/SWC harness which plugs into the back of the Alpine 8" LCD touchscreen; there is a 22-pin connector which plugs in the radio replacement interface module on the other end. This harness also includes a foot brake wire (yellow/black), remote turn-on wire (blue/white), and chime module harness.
