About the Kenwood KDC-BT858U
A sleek and functional look
A sleek and functional look
Kenwood designed their KDC-BT858U CD receiver to be a simple, elegant control center for entertainment in your vehicle. A multi-function control knob and a few buttons give you quick access to this receiver's long list of features, including hands-free calling, music streaming, Internet radio access, and more.
Bluetooth® lets you concentrate on driving
Bluetooth gives you hands-free calling convenience, plus a wireless connection to the songs stored on your compatible music player. If you're an Android® user who's had Bluetooth pairing issues in the past, you'll love this receiver's simple, secure pairing (SSP) technology. If you're an iPhone® aficionado, the KDC-BT858U gives you full Siri Eyes Free control with compatible Siri-equipped iPhones.
Pair your compatible phone to the KDC-BT858U and you can talk hands-free by simply touching the dedicated "phone" button when a call comes in. And the receiver can reply automatically to text messages to let your contacts know that you're busy driving. You can place the external Bluetooth microphone in an optimal location within the vehicle for better hands-free communication.
The display's the thing
You can select display and illumination colors that match your car's dash or your mood — your choice. If you're of a "certain age," you'll be happy to know that you can switch the 3-line display to a 2-line format with a larger font — great for phone numbers, song titles, and source data. You can also tone it down to just show the clock or a blank display. Dust covers conceal and protect the CD slot, aux input, and front USB port.
Use this Kenwood's controls to play your favorite Internet radio stations.
Stream radio from your phone
If you enjoy Internet radio on your iPhone or Android phone, you'll really enjoy playing music from Pandora®, iHeart Radio®, and Aha™ radio on this great-sounding receiver. You can scroll through your stations, bookmark songs, and give a thumbs-up or thumbs-down right from the receiver's face.
Two versatile USB ports
Here's a cool feature from Kenwood — Drive Change allows you to connect a memory card reader or USB hub to the Kenwood's USB input and select music from up to five memory cards or USB flash drives. The receiver's front and rear USB ports also allow you to access and control the music stored on your iPhone or Android phone. And if you store your music on thumb drives, the USB ports can handle those too.
Sculpt your sound
This receiver includes an impressive suite of sound adjustment tools, which let you refine your audio experience. You can tweak the 3-band parametric equalizer, the built-in frequency filters, and the 3-level bass boost to find your perfect sound. The KDC-BT858U's Sound Reconstruction feature gets the most out of your compressed audio files. You'll find a full set of 4-volt preamp outputs that'll send a clean, noise-free signal to all your amps.
Want to keep your car's steering wheel audio controls?
In most vehicles, you can use an adapter (not included) to connect your vehicle's steering wheel controls to this Kenwood stereo. Connect a few wires, program the adapter for your car and this Kenwood, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to five Bluetooth-enabled devices to the Kenwood head unit with a maximum of two Bluetooth phones and one Bluetooth audio player connected at one time (but only one can be used at a time). You can even pair your Apple iPhone by simply connecting it to the Kenwood head unit via USB and following a single prompt on the head unit's display.

You can answer the call from the head unit's front-panel controls, or setup the head unit to automatically answer the incoming call immediately or after 1-30 seconds. The KDC-BT858U also supports the Call Waiting function, so you can answer another incoming call while suspending the current call you are on.

Each preset has its own level settings for bass, midrange, and treble . You can choose from the following preset EQ curves; Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User. The Drive EQ mode is an EQ preset that helps reduce road noise. The User mode allows you to manually adjust the head unit's Bass (200Hz) , Midrange (2.5kHz), and Treble (12.5kHz) level from +/- 8dB.

- Sound Reconstruction: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.
Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0 (-8 to +8 for Aux source).
Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.
