Alpine X308U

$449.00 USD

See things more clearly on an 8" touchscreen

Your pride-and-joy vehicle's no place for a regular old touchscreen receiver. Alpine's X308U navigation receiver sports an 8" display, so you can get the big picture of your maps and album artwork while you're driving (and enjoying video while you're parked). You can enjoy tunes from a USB source or your smartphone, thanks to Apple CarPlay® and Android Auto™ compatibility. Built-in navigation ensures you'll be able to find your destination even when you're out of cell range, and you get the usual array of sonic upgrades and other goodies from Alpine, to boot.


Alpine X308U digital multimedia navigation receiver

A bigger screen, but will it fit?

Since there's no disc player, the X308U's chassis is smaller than most comparable touchscreen navigators. The chassis is likely to fit in many vehicles, and you'll have more room for wires, adapters, and other necessities behind the receiver in your dash opening. Compatible dash kits for this radio may be very difficult to locate — if you can't find a dash kit for your vehicle, custom fabrication by professional or experienced installers is recommended.

Works with both Android Auto and Apple CarPlay

The X308U's compatible with both Apple CarPlay and Android Auto, so you and your passengers can enjoy messaging, mapping, tune selection, and much more from your smartphone without touching any screens. Both platforms work with voice commands, which you can activate by speaking a keyword or pressing the dedicated "Voice" button on the stereo's bezel. You can get stuff done without being distracted by your phone. Get more info at and

Improved user interface

Alpine had a real winner on their hands with 2017's X208U 8" navigation receiver, but they've found a way to make things even easier on drivers with this car stereo. The response time to commands is much quicker, so you're never behind the action. And the user interface's upgraded to get you to your preferred display even faster, so you don't feel like you're wasting time.

Four-way swipe control lets you immediately pull up navigation, Bluetooth®, entertainment sources, or settings, while dedicated hard keys also help you find the right screen with ease. And the X308U's capacitive 8" touchscreen gives you pinch-to-zoom command of your maps and other screens, so you're able to get the best view.

Mapping you can rely on

Take a trip nearly anywhere in the U.S. or Canada, and you'll enjoy detailed road maps and over six million included points of interest. You'll also have time-saving assistants like lane guidance, realistic views of complicated interchanges, and 3D representations of buildings, landmarks, and terrain to help keep you on the correct course. You'll even receive real-time traffic reports in most metropolitan areas for as long as you own the Alpine, at no additional cost.

Works with Alpine Go! from your smartphone

Say you're browsing your phone while at the office and you come across a great new restaurant you want to check out. You save the location on your phone's Google Maps app, but when it's time to get into your car, do you want to go through the trouble of searching for it again on your receiver? The free Alpine Go! app sends saved locations from your phone right to the X308U, so you can have all your favorite spots loaded and ready to go before you hit the road.

Get to your favorite functions in a jiffy

The receiver's "Favorites" button gives you quick access to features you use frequently, like contacts, radio station frequencies, sound settings, and destination searches — anything you'll want to pull up rapidly, including beloved CarPlay and Android Auto functions. One touch adds your choice directly to the favorites menu. Your favorites are tied to your phone's Bluetooth profile, so the X308U recalls your favorites automatically when you get into your vehicle. When the stereo detects two users at the same time, it can offer split-screen access to both users' favorites, so either user can gain control of the action lickety-split.

HD Radio

HD Radio®, Pandora® Internet radio, and more

The X308U offers a wide variety of entertainment options, even without a disc player:

  • HD Radio reception: You'll enjoy crystal-clear sound quality from participating AM and FM stations, including FM that sounds almost as good as a CD. Plus, you'll see station and song info on the screen.
  • Pandora Internet radio and iPhone and iPod® control: Easy on-screen control through Android Auto and Apple CarPlay, and you can also control Pandora through Bluetooth with your Android device if your device isn't connected.
  • Satellite radio compatibility: You can add SiriusXM programming to the receiver with an optional tuner and your paid subscription.

Alpine accessories give you even more ways to play

The X308U does a lot right out of the box. But these Alpine accessories can add even more functionality to what's already an amazing receiver.

Add cameras: Cameras are fast becoming a must-have car accessory, and adding Alpine's KCX-C250MC selector to your X308U will let you take full advantage of its video capability by connecting up to three cameras (not included). It also works with the Alpine KCX-C2600B dual-camera selector.

Add driver assistance: This receiver works with Alpine's DVR-C320R 2-camera system with built-in Drive Assist, so you can get safety features like lane departure warnings, front collision warnings, and front car movement warnings along with recordable HD camera views from the dash, interior, and rear of your car.

Add another HDMI input: The X308U has one HDMI input, which is impressive enough, but in today's world, you might need more. If you want to use both your smartphone and another video source through your receiver's display. Alpine's KCX-630HD HDMI Switcher gives you a pair of HDMI inputs, plus a USB port for providing power to your smartphone or tablet.

Add a disc player: If you still want to be able to play discs occasionally, check out Alpine's DVE-5300 DVD player. This compact, single-DIN player fits into discreet spots in your vehicle, like a glove box or under a seat. With an HDMI connection to a monitor and the option to channel audio through an optical output, you'll get the best possible picture and audio.

Customize your truck: If your truck or SUV is equipped with an aftermarket winch, light bar, air compressor, or other electrical accessories, you can control that gear through the X308U, too. Just add an optional Alpine KAC-001 external accessory controller to your order.

Tweak your audio with the TuneIt app

The X308U also works with Alpine's TuneIt smartphone app, which is a real time-saver for making audio fixes. For starters, it allows you to create a user profile with info about your vehicle and Alpine system, including speakers and subs. You can then follow simple instructions for adjusting sound settings for your specific vehicle (if available), or choose from pre-made settings within the app designed by Alpine for both the vehicle and your speakers.

You can use your phone's touchscreen to make the changes to the 9-band parametric equalizer, crossover, and time correction with just a fingertip. You can then share your system and settings with other TuneIt app users, and see what they've done as well. You can link your TuneIt account to your Facebook account and get notifications through social media.

Treat your ears with low end

The TuneIt app also offers Alpine's Bass Engine SQ tuning feature, which lets you determine which low-frequency characteristics you want to emphasize. It automatically adjusts EQ, sub level, and crossover settings to give you the kind of bass you desire without hassle.

And speaking of great sound, this Alpine lets you play FLAC audio files from your thumb drive, so you can enjoy your lossless tunes as you travel.

Make it a night at the movies

Adding a disc player or have a thumb drive with video files on it? You can use the receiver's HDMI connection to connect to send video to your vehicle's rear-seat entertainment system to keep your passengers happy. Independent dual-zone video control lets you watch movies up front and send different video content to the back while you're parked.

iDatalink Maestro lets you keep your factory extras

The X308U offers compatibility you won't find in many other aftermarket radios, thanks to the iDatalink Maestro module (not included). In a wide selection of vehicles, this module lets you keep factory features that you'd otherwise lose when you install a new radio. You'll also be able to check out engine performance data and other vehicle info on the Alpine's screen. Once you've identified your vehicle, you'll see the iDatalink module offered on the way to the Shopping Cart if it's compatible.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

Compatible dash kits are discontinued — we recommend custom fabrication by experienced and/or professional installers.

You'll need a wired connection to your parking brake to access settings and other features on this receiver. Your parking brake must be connected and set in order to view video on its screen.
