Quality Android Head Unit
344695
I am a 62 year old electrical engineer in the central part of the U.S. that has been installing automotive electronics off and on since age 15, mostly for friends and family.  The information supplied with this head unit for installation was precise and easy to understand.  I installed this unit in my 2006 Toyota Tacoma utilizing a Metra double DIN dash kit.  There were no issues.  I had been looking at various Chinese made head units for about 6 months and have been skeptical about both hardware quality and bugs.  Since my returns experience with Amazon has been excellent, I decided to try this head unit.  Quality of the hardware and connectors seem to be excellent.  All features are working flawlessly and as advertised.  The unit looks great in my Tacoma.  With this head unit, I installed a backup camera from Esky.  It works very well.

I really enjoyed these android base tablets.  Not only do they have a sleek design, they are extremely easy to operate and the picture quality is definitely 1080p when playing a movie.  Also, did I mention that installation was so easy that even a child can do it and I'm not just saying this.  If you are thinking about purchasing Headrest Screen for your vehicle with easy installation, great picture and sound quality, I challenge you to go out and purchase these.  You will not be disappointed.

I'm more than impressed.

Featurewise, this small device is everything one would need to carry an A2DP Bluetooth enabled device's audio stream to a vehicle's stereo system - whether the stereo system were auxiliary-port equipped or not.

What it's got:

* 3.5mm Line-In Jack, for throughput
* 3.5mm Line-Out Jack, for directly connecting into a stereo system's Line-In
* USB Charging Port
* Full-Band FM Frequency Transmitter. Pressing the Tuner button also acts as the
  Device's Volume Control
* Bluetooth Receiver, With Next/Back/Stop/Play Controls for Such-enabled BT Devices
* Handsfree Bluetooth Call Answer/Call end for Such-enabled Devices.

I bought this device specifically because it had a line out port to patch into the Auxiliary Port on my vehicle's stereo system, so I can use my Motorola Droid's MP3 player via bluetooth.  The sound is crystal clear, pairing was easy, and it does as advertised: If a call comes in, the MP3 player pauses, and the BTC8 takes over instead of the speakerphone option while the Droid is in the car mount.  The caller is patched in through the car's stereo system, and the mic on the BTC8 is 10x more clear than what is native on the Droid.

I've even tried it using the FM Transmitter feature- Works like a charm.

The Cons:

There aren't really any cons, but I figure I should mention.  Like with any Bluetooth audio device, you do have to reset the volume control on the BTC8 in order to get both it and the connected device to sync audio levels - this is the same if you use the FM Transmitter.  You do have to turn the BTC8 up all the way in order to pick up an acceptable level of audio, but that is with any FM-Transmitting device.

Also, the 12v DC Stalk is longer than you think - while it is completely flexible, of rugged design, and stable, the one thing I would have wished for is for it to be shorter on merit of I can't find a suitable angle to stay out of the way of all the buttons on my console.

The Audio Line in/Line out ports are on the top of the device, while the USB charging port is on the bottom. It would have been better design to have them all along the bottom, but I can live with it.

All in all, I couldn't be happier with it! I walk out to my car, mount my droid in the GPS dock, enable bluetooth, Sync volume, and off I go listenin' to my tunes. :)

Got the HRT microStreamer USB DAC to play FLAC files from my smart phone. The unit's build quality and audio performance is top notch all the way up to 96k - 24bit source material. Its small size lends itself to portable music listening through its low impedance headphone output with a digitally controlled analog volume control. As a bonus, It also has a very low distortion, high gain (2.25V) fixed line level output perfect for feeding audio to a home stereo.
The only caveat was that I have an older Samsung Galaxy S3 who's version of Android does not support USB audio. Custom audio software was needed to bypass the Android operating system as well as take advantage of the HRT's asynchronous data transfer protocol. Currently using "USB Audio Player Pro" from "eXtreamsd.com".  When all is said and done, you get High-End sound at a Mid-Fi price ($151 from Amazon).

Great head unit. The interface is a bit slow. But the Bluetooth connects very fast to devices that are already registered. And the power is amazing. Im Upgrading my stock door speaker to make the most of the power this head unit brings.

I purchased this product to use with a Samsung Galaxy II Skyrocket (Android version 2.3.6) in my 2002 Dodge Dakota for Bluetooth music and hands-free calling.  I'm very happy with this purchase.

The device has a sufficiently strong FM transmitter that it can overcome the nearby FM radio stations that normally cause static and poor sound quality with this sort of FM adapter.

Music quality through the car stereo is good for a Bluetooth device, although a little muddy.  Song titles and artists appear on the car stereo display (you need an FM receiver with RDS for this to work), as well as on the device's screen.  Voice quality for hands-free calling is good on the reception end (my end).  I've been told by people I'm calling that my voice sounds a little muffled, but that's probably true for every automotive hands-free solution other than a headset.

Construction quality of the device seems good.  The controls and menus are reasonably intuitive, and well-explained in the short manual that comes with the device.  Pairing the device with my phone the first time was straightforward, and has worked automatically since then.  Text on the device display is legible, but not beautiful.

I haven't tried the analog, SD or USB inputs yet, or transferring my phone's address book.

Excellent way to get old and new android phones hooked up to an Android auto car stereo

Good head unit especially for the price..... The display during the day sucks though. The Bluetooth is great and works every time!

Really good headunit. Definetly adds sound quality over stock H/U.  The cool feautures like appradio and dvd player all work as an added bonus. Samsung s4 connects to radio well

Upgraded to this from my OEM Ford stereo since the CD player didn't work. I've still only used the CD player about twice since I've had this because the bluetooth feature is so useful! My Moto Z Force Droid phone syncs to the bluetooth automatically as soon as I start the truck and all I have to do is hit play on my Google Play phone app and drive. The sound quality is far improved over the factory stereo. Perfectly clear sound from the OEM door speakers and the microphone accessory worked great for taking calls on the road. Most people I talk to can't even tell I'm driving and talking to them through the stereo system. I could probably upgrade the speakers to something better tuned to the 100w output and get better sound quality but I'm not sure I need it since I'm so pleased already!

Not sure where to start with this head unit.  It does everything a car stereo should and then a lot more.

Things I've tried:
Mobile Hotspot with my phone allows internet access while driving (Trigger app lets me turn my mobile hotspot on automatically when my phone connects to the head unit via bluetooth)
Google Maps works great with head unit's GPS and mobile hotspot
N64 emulator works great
GTA Anniversary editions (GTA3, Vice City, San Andraes all work great)
OBDII unit connects and works great with Torque app
USB Hub for connecting more than two usb devices

There are a couple drawbacks, but most of them have workarounds.
Can only use Bluetooth for ODB devices and connecting to your phone/tablet for (no bluetooth keyboards, mice, controllers, etc...).  Workaround is to use an RF wireless usb device instead of a bluetooth device.
No physical next/previous buttons (I don't like getting finger oils on the screen).  Workaround is to use a mini wireless usb keyboard with media keys.
Volume knob is unresponsive for a few minutes after head unit cold starts (When you turn the car off, the screen will turn off but the unit will stay on for a little bit.  The amount of time is adjustable in the settings.  Mine is set to stay on for two hours.  When you turn the car back on before the unit has completely shut down, the volume knob does not have a problem).  The workaround is installing a custom rom.  I have installed Malaysk and it hasn't completely fixed the problem, but it is a lot better.

I have to give credit to the seller Volsmart.  About a month ago, someone got in my car and started to remove the stereo.  They didn't get it out, but they did leave a big scratch in the screen.  I contacted Volsmart and they sent me a new digitizer and helped me to get it installed.  Their customer service rep Joe was very responsive via email.  Each time I emailed them, I had a response within 24 hours.

Android Auto is great, the audio is great, My AM/FM reception improved.

Replaced a stock head unit in a 96 4Runner -- had the install done by a local shop.
Sounds great.
Bluetooth works great.
Radio antenna control is horrible -- it only goes up partway about 50% of the time.  Thankfully, with BT working, I just listen to Pandora anyway.
The UI is kinda s***ty, but once you get BT configured, it doesn't really matter.

It would be nice that this device would be able to
 1- Auto start when it gets power.
 2- open the default music player on my android phone on a single click.
Currently, I have to have the app open in order to push the button to start playback.
In my Ford when I start the engine it automatically starts playing my phone's music (if I was playing it when the car was turned off), I expect the same from this device.
Nice quality phone calls, good quality audio with APTx and very easy to install and use. The perfect addition to my car.

Easy to install. It is a very simple straight forward head unit. I'm just going to put a thumb drive in it and plug my phone into it, so there is no need for a CD player.

I installed this unit to replace the stereo in a 24' sport boat.  To me, the head unit of a stereo system is not as important to sound quality as really good speakers and a well-matched amp, so I was looking for a decent quality unit with the inputs/outputs I needed at a good price.  This unit has an excellent combination of inputs for subwoofer, amp, remote, and has all the features needed to integrate into a really nice system (such as subwoofer level control, a remote amp on/off wire, etc.)

Personally, I would think the head unit manufacturers would stop making so many different models with CD players as part of the unit as I doubt many people actually carry CDs around as opposed to plugging in an iPod, but, this is certainly not a negative feature about the product; just an observation.

The item description is a little ambiguous, so, to be clear, the unit does not control an iPod or other MP3 device when plugged into the AUX input.  It plays the devices just fine, and the ability to remotely locate the spot where you'd like to plug in your MP3 device is great.  Some head units/remotes will actually control your iPod; this one does not.  This was not a negative to me, but if you're looking for a unit that will control your iPod, choose a different unit.

Overall, I would recommend.
