Keep your factory look and controls

This Restyle kit lets you install an oversized Alpine receiver in your vehicle 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 vehicle.

Plug it in and go

You'll need to hardwire your new Alpine to the car's parking brake. Then, the included wiring harness plugs directly from the Alpine receiver into your vehicle's factory wiring harness — no extra splicing or soldering needed. This Restyle kit works with both GM's regular and Bose® audio systems (but not the Bose® Centerpoint system), and it allows you to keep your OnStar functionality. The package also includes a steering wheel audio control interface — no programming necessary, just plug it in and go. Warranty: 1 year.

Note: This Restyle kit will not work with factory Bluetooth® or the factory satellite radio tuner. It will also not work with the factory Bose Centerpoint system.

Note: Sorry, Crutchfield cannot ship Alpine products to Guam or Puerto Rico.

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.

Looks amazing and the install is as easy as it gets.

Well worth it

2008 Chevrolet Avalanche
Crutchfield Customer Review (What's this?)

Looks amazing and the install is as easy as it gets.

Pros: Wiring harness was a perfect fit for my 2007 Avalanche and the install took me less than 30 minutes from start to finish.

Cons: Instructions could be a little better as there are actually connections not even mentioned in them. I had to call Alpine tech support but the guy helping me actually had a harness right in front of him and we solved the problem in under 5 minutes. The plastic trim piece will chip on the edges if you are not careful. I had a small piece chip out of mine on the side when popping it into place. I found it much easier to put it on by starting at the bottom and working my way up instead of top down.

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-GM8W-O Perfect F.I.T. Installation Package allows seamless integration of the Alpine 8" LCD touchscreen navigation head unit in select 2007-up GM Trucks/SUVs with OnStar (with or without Bose). Not compatible with Premium Bose systems (Y91/Y92/Z75), Fleet trucks, or upper-dash OEM stereo locations. This Perfect F.I.T. Installation Package will not retain factory Bluetooth functionality or factory SiriusXM satellite radio tuners.

OEM-Like Appearance: The KTX-GM8W-O Perfect F.I.T. Installation Package has been specifically fitted and engineered to fit select 2007-up GM Trucks/SUVs 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.

Vehicle+Radio Harness: This Perfect F.I.T. Installation Package comes with a GM LAN Stereo Replacement Interface Module (KCX-SRMGMO) and vehicle+radio harness for simple installation between the Alpine 8" LCD touchscreen navigation receiver and your 2007-up GMC Truck/SUV. You get all the necessary harnesses and adapters in the box to install the Alpine 8" LCD touchscreen navigation navigation receiver in your 2007-up GMC Truck/SUV.

Note: The vehicle+radio harness contains two Molex connectors which plug into your GMC Truck/SUV's factory radio harness. There is also an 8-pin connector which needs to plugged into either the vehicle+radio harness' Bose or Non-Bose port (based on your vehicle). On the other end of the harness is a 20-pin connector, 5-pin connector, and 3-pin connector which plug into the included OnStar/Steering wheel remote interface module. On that same end of the harness is a 16-pin Alpine radio connector which plugs into the radio connector port on the back of the Alpine 8" LCD touchscreen navigation receiver. In addition, you will need to make two hardwired connections between the supplied vehicle+radio harness and your vehicle's Parking brake (Yellow/blue) and Foot brake (Yellow/black). There is a remote turn-on lead (Blue/white) to connect an aftermarket amplifier.

OnStar Compatible: The included GM LAN Stereo Replacement Interface Module allows you to keep total functionality of your GM vehicle's OnStar system.

Steering Wheel Controls: The included GM LAN Stereo Replacement Interface Module also lets you keep your vehicle's steering wheel remote controls. For 2007-up GM vehicles with factory steering wheel audio controls, the KTX-GM8W-O retains the capability to control the Alpine 8" LCD touchscreen navigation receiver's volume, source, and playback controls. There is no additional programming required, simply plug & play.

Note: The 3.5mm connector of the steering wheel remote interface cable plugs into the 3.5mm remote input of the Alpine 8" LCD touchscreen navigatio nreceiver.
