Boss Audio 812UAB
Digital media receiver
Our take on the Boss Audio 812UAB by Crutchfield's Jon Paulette
This digital media receiver will not play CDs. If you want to play CDs in your vehicle, we offer a wide selection of CD receivers.
Go digital without going broke
If you're ready to ditch that album full of scratched-up CDs and go digital, Boss Audio's 812UAB digital media receiver offers an impressive array of features for its price range, plus a variety of connections for your devices.
Plenty of ways to play
This double-DIN (4" tall) receiver can fill a big space and provide plenty of entertainment. You can pop an SD™ card full of music into the slot behind the front panel, or enjoy your local AM/FM stations. Plug a thumb drive into the front panel USB port to enjoy MP3 files, or use the aux input to connect a portable satellite radio tuner. That front panel aux input will also work with a portable CD player -- if you haven't quite finished digitizing everything, you've got a backup plan in place.
Buying a budget receiver doesn't mean giving up conveniences like built-in Bluetooth® connectivity. With the 812UAB, you can take calls or stream music stored on a smartphone without taking your hands off the wheel.
Plenty of great features
You can use the 4 EQ presets and the tone controls to shape the sound, while a set of RCA outputs gives you room to expand your system with an outboard amp. Handy illumination controls allow you to adjust the brightness of the display. It even comes with a remote control for your backseat passengers.
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.Smartphone note: If you're going to use your Android smartphone with this receiver, be sure to check "Details" for compatibility information.
The equipment was shipped to me the next day. The connection pretty easy. Fits perfectly with the new bezel. The sound is very clear.

Don't know. It fit very nicely in a 2000 Honda Civic, [ Gerry May 13, 2014 ]
Should fit any Ford with Double Din opening. I actually installed in a 2006 Sterling Class 8 truck( same as Ford) . I needed a shallow radio due to air lines running in dash. Works great and very pleased with features for price. [ CRAIG May 13, 2014 ]

Yes it can play an iPhone 5. I haven't tried playing music from the USB yet, but AUX and Bluetooth work great. [ Brian Mar 12, 2014 ]
It should play as long as the phone and the radio establish a connection with each other which it should by using the usb cable [ ERWIN Mar 11, 2014 ]
No this cant play Iphone, Meaby w/ Blue toot! [ JULIAN Mar 10, 2014 ]
I have not been able to install it yet. [ Christopher Mar 10, 2014 ]
I'm sure it can... I can play music via USB on my HTC. I believe when it says it doesn't have controls means that it doesn't have special abilities, like using Siri with the system. Once again, though, I'm not entirely positive, I'm just assuming. [ Remington Mar 10, 2014 ]
I was wondering if I brought this receiver for my 2002 trailblazer. It has remote start, but I don't believe it's factory. The reason I believe it is aftermarket, is because the remote start unit has a small device right above the rearview mirror. So I don't know if it has anything to do with the factory stereo or not. I guess my question would be, if I installed the boss 812 would it interfere with the receiver in any way? [ jason Mar 29, 2014 ]
Yes. The receiver has RCA pre-amp outputs which will connect to the RCA inputs on your amplifier. [ Matthew Jan 28, 2014 ]
Yes [ MICHAEL A Jan 20, 2014 ]
Does this have AM/FM radio on it also going in a 2005 Silverdeo 1500 [ lee justice Mar 10, 2014 ]
It is near the APS button on the receiver. You can see the location of the microphone on the first page of the manual here: http://a248.e.akamai.net/pix.crutchfield.com/Manuals/104/104812UAB.PDF [ Jeff Jan 20, 2014 ] Staff
Kris S, the bluetooth on this unit is awesome. I have not had a single issue using this unit. The microphone for making calls actually sounds better on this unit than on the JVC that it replaced. For the money you can't beat it IMO. [ RICHARD R Jan 14, 2014 ]
Ray W, I have an I-phone 4S. The phone will only make calls via bluetooth. When I connect the phone to the unit, the phone asks if I trust the computer. I click trust and the head unit then refuses to acknowledge the I-phones is even there. I have tried selecting don't trust and same thing. I only use my cable/USB to charge my I-phone. I use bluetooth for everything else. [ RICHARD R Jan 14, 2014 ]
I don't know. It still hasn't arrived. [ KEVIN Jan 13, 2014 ]
I have only used bluetooth, and it is great. My phone is recognized as soon as I get in my car, even if I actually have the radio tuner selected. I haven't been able to figure out how to use it with usb connection, but if that is important to you, simply call Crutchfield, these guy are great! [ Ramiro Jan 13, 2014 ]
Works both ways. [ Brian Jan 12, 2014 ]
Haven't received it yet. Sorry [ abbas Jan 12, 2014 ]
Sorry. I gave the stereo as a gift to my son-in-law. So far he hasn't installed it. [ Harold Jan 12, 2014 ]

Will I lose factory controls such as remote start, and other functions that are controlled by the factory stereo! [ lando Dec 16, 2013 ]
This unit does feature Bluetooth streaming for music, so you will be able to stream music from your iPhone. [ Jeff Nov 29, 2013 ] Staff
