Alpine i905D-F - Freestyle Head Unit

The Alpine Freestyle systems have been created to cover the growing demand for a custom installation system. Freestyle can be used especially for vehicles where no regular radio or navigation fits and no solutions are available. It is then up to the skill of the installer to use the Freestyle system to create a great installation for the vehicle.

The 4th generation Alpine Freestyle media system features a 9-inch high-resolution WXGA touch-screen with 1280 x 720 pixels resolution, extensive media options including wireless Apple CarPlay and (wired) Android Auto compatibility. It also features 2 USB ports as well as a built-in DAB+ digital radio tuner.

You also bring exceptionally good sound quality into your vehicle: the Alpine Freestyle system is among the world’s first Head Units featuring a built-in Class-D amplifier and has a wide array of professional sound tuning functions, such as 2-way X-overs, a Parametric EQ, digital time correction and much more.

Product Features

Freestyle System for Custom Installations

Alpine freestyle systems have become very popular among professional installers, allowing them to create media system installations for vehicles, that are incompatible with 1DIN or 2DIN systems, and for which no car specific solution is available. The new i905D-F uses the same platform technology than our latest Halo9 system, giving the customer a 9-inch hi-resolution touch screen, wireless Apple CarPlay and (wired) Android Auto capabilities, 2 USB ports, built-in DAB+ and Bluetooth, as well as many more amazing features to build a professional entertainment system.

All Parts Included

The i905D-F Freestyle system includes a high-resolution 9-inch WXGA touch-screen with 1280 x 720p resolution, fully customizable key panels, a media receiver, GPS antenna, wiring kit and a installation frame. This gives the installer all parts needed for a good custom installation.

Interchangeable Keys

The 2 key panels can be installed horizontally or vertically, depending on the installation position. The key positions can also be assigned individually due to the interchangeable buttons, while the key caps can be easily removed to change their position. The can also be rotated to allow vertical or horizontal installation. You can easily adjust the illumination colour of the control buttons to 6 different colours and to 2 brightness intensity levels.

9-inch WXGA HD Display

The large, 9-inch WXGA touch-screen display features a resolution of 1280 x 720p and includes over 2.7 million pixel elements - making icons, menus and visual content extremely crisp and vibrant in your dash.

Wireless Apple CarPlay

The i905D-F “Works with Apple CarPlay” wirelessly and lets iPhone users make and receive calls, access and write text messages, play music, and get direction in a way that allows them to stay focused on the road. Apple CarPlay is accessed through the capacitive touchscreen or the mic button to activate Siri voice control. Due to the WiFi connection, you can keep your iPhone in your pocket and do not need to plug it in all the time (except for charging).

2x USB Ports

While the i905D-F is mech-less (no built-in CD/DVD drive), you still have plenty of entertainment options. 2 USB ports located on the back of the unit allow you for example to connect one mobile device for charging, while the other USB port is used to plug in a USB stick or hard drive to access audio and video files.

Bluetooth Hi-Res Audio Streaming

Wireless Bluetooth connection to your smartphone or Bluetooth-enabled digital audio player is also possible, thanks to the built-in high-end LDAC standards. With LDAC, you can stream your audio content, including high-resolution (Hi-Res) audio, at a maximum bit rate of 990 kbps via Bluetooth. This makes this Alpine Head Unit ideal for hi-res audio and streaming services with high sound quality. The transmission bit rate is constantly adjusted with this technology to ensure a stable connection even in harsh environments, depending on the network conditions.

World’s First Head Unit With Built-in Class-D Amplifier

The i905D-F is the world’s first aftermarket Head Unit featuring a built-in 4x 50 Watts Class-D amplifier – allowing excellent, high-end sound reproduction with highly reduced noise or phase shift. The key benefit of Class-D amplification technology is its high efficiency of about 90%, compared to 50 - 70% of Class AB amplifiers. New high-speed fans with internal heat sinks keep your i905D-F cool - and the music playing.

Enjoy Excellent Sound Quality

Featuring a 56-band Parametric EQ in the advanced mode, a 2-way digital X-over, 6-channel digital time correction and several Bass Engine SQ and MediaXpander sound tuning options, you have excellent tools at your disposal to tune your i905D-F and the attached amp / speaker system to perfection. But we didn’t stop there: The i905D-F is Hi-Res Audio certified and can decode and playback Hi-Res Audio files up to 96kHz / 1.536 kbps from USB sources in uncompressed supported formats such as FLAC, WAV and APE.
