Worth it for its price range. A+
This was decently priced stereo replacement for my old car with old school and modern applications. Since I already was upgrading most of my old speaker/stereo set up in my old car might as well update the single din stereo. This worked perfectly. And can't beat the price.

So far so good.
My old aftermarket radio died and this was the cheapest one I found. It works for now and sounds pretty good to me. Haven't used the Bluetooth capability.

Very old tech, kinda crap honestly
So value for money I put as 2 stars. Why? Its 2020, DVD players should be able to do quite a bit more than just play DVDs. This has a USB function to play what ever is on the USB. The menu (all menus on this are crap) for the USB is trash. Its set up like a windows 95 file system which only can see a few file types. I had 30 movies and this only saw 4. The remote has a zoom function which only mutes while the mute button also mutes!? The rear auto output does not work. Lucky for me my amp has a 2 channel or 4 channel input switch so that saved the day. Speaking of which, I dont believe this pushes much to the amp, weak signal. The signal it provides to the TV is pretty crappy too. Again, its 2020 so why no HDMI? Now I understood the VGA going in but I guess I expected more. Overall, dont waste your money. Spend a bit more and get something more up to date with HDMI.

Device broke within 3 months of purchase
So I think this device broke due to the mild bay area heat wave. I live in California, near San Francisco, this device started touching itself or acting as though someone was pushing the buttons a few days ago. Coincidentally we had a heat wave, where temps reached around 105 degrees in my area, thats still pretty cool compared to the rest of the country since we're close to the ocean and doesn't come close to most peoples general summer temperatures. I assume something must have melted inside the device because thats the only thing I can think of for why it is acting as though someone is touching the device. I've reached out to Boss support, I guess we'll see if they care that their device broke. Also apologies for the video, I had just gotten home from grabbing food and as you can tell the issue is kind of intermittent, so I took the video while I had the chance. Edit: So after contacting the seller on amazon, they told me to reach out to BOSS directly as they handle the warranties. So I reached out to them, they wanted me to destroy my old unit and take pictures as proof of doing so. I asked if they'd be willing to send me out just the faceplate as I thought that was what the issue was, new face plate has seemed to fix the unit. It's been about a month since I replaced the unit, hopefully it doesn't act up again. but I guess we'll see if next year if it'll survive the summer heat again. Edit: 1 year update, as I predicted the item died again. About a week ago the item behaved as though someone was touching the skip buttons for a few seconds, and then the skip buttons stopped working. At least this time it appears only the skip buttons stopped working, it doesn't appear to be touching itself. Newspapers are calling this the coolest CA summer in decades as of july 2025, so seriously do not buy this item.

Good but could be better - Update: USB stopped working :(
My old truck needed a new stereo, and after reviewing the PDF manual, the specifications, and the sale price, I picked this one. Installation went remarkably smoothly - the instructions are clear on which wire is what, and it slid right into the rectangular DIN slot. The display is bright and colorful, and the sound quality is remarkably good. Bluetooth pairing is fast, and in Bluetooth mode the display does scroll the title, artist, and album information for the track while playing. So what's not perfect about it? First, the PDF manual in the Amazon listing said that this model has a SD card slot under the faceplate. I like having a SD card loaded up with all my .mp3 files for when I don't want to mess with Bluetooth pairing or the radio. (Narrator: there is no SD card slot on this model, regardless of what the PDF manual in the listing says.) I loaded up my files on a USB stick instead and inserted it in the front USB slot. And waited. And waited. In USB mode, if you have a lot of .mp3 files on the USB drive, it can take up to 30 or more seconds for the stereo to start playing the first track, and up to 10 or more seconds between tracks to seek the next tune. If you push the RDM button, it will indeed randomize the play sequence, but once you turn the unit off or switch to a different mode, it turns off the randomization mode and starts playing in file sequence again once you go back to USB mode (hey, why am I hearing all these songs in a row about "goodbye"...?) And in USB mode, the stereo will not pull the track details built into the file, and will only show the track file name - the title, artist, and album are all blank. So, yes, I'll keep it, and I'm happy with the price, and it's better than the one I replaced - but it isn't 100% of what I expected, and could be better. Update: After only a few weeks of very light use, the unit no longer recognizes USB drives. It's gone from a long delay when switching to USB mode to an infinite delay - the display just shows "USB", but never starts playing music, even after hours of waiting and removing/reinserting the drive. I tested the USB drives and they're fine. Another disappointment. At least the Bluetooth seems to be working (within a relatively short range) - for now.

Works well...so far.
Installation is relatively easy which included hooking it up to previously installed 300 w amp...needed a adapter harness for my 99 Miata but that's typical. All the functions are operational as advertised, Bluetooth is lightening fast. I would agree with others who noted the CD load time is tad long...but that's just a quibble. Economical, but really solid sound output. Overall, a versatile little unit.

Das Audiokomplettpaket von BOSS ist perfekt. Es ist alles dabei, was man für den Einbau benötigt! Inklusive 2 Lautsprechern und eine Anleitung (englisch). Der Einbau ging ruck zuck und ohne Probleme. Keine 30 Minuten zu Zweit und das Radio war amt Lautsprechern verbaut. Der Klang ist für den Normalnutzer super. Die Funktionen das Radios sind perfekt. Es hat alles was man braucht. Das Radio ist schlicht und nicht aufdringlich! Die Boxen haben einen guten Sound! Wer ein tolles Radio mit Boxen zu einem unschlagbaren Preis braucht, dem kann ich dieses Komplettset wärmstens empfehlen! Ich würde es jeder Zeit wieder kaufen. Ich bin zufrieden! Von mir gibt es 5 Sterne Plus :-)

Es perfecto, lo uso más por bluetooth pero suelen conectar usb y auxiliares, las llamadas se pueden atender a través del mismo y la calidad del audio/micrófono es buena. Llevo ya un año con el y a toda mi familia le encanta

Ya he comprado anteriormente estéreos de esta marca y la verdad siempre he quedado satisfecho, en este caso es un diseño muy bonito, los materiales son de buena calidad y ofrece muchas opciones de conectividad lo que lo hacen destacarse de su competencia, además el precio es accesible por lo que me siento muy contento de haber realizado la compra, lo recomiendo totalmente.

i was not sure when i bought it as its really low price, i installed it in my tractor the other day and wow, i think i hit a jackpot. i don't think i will trade for any other even if it was double the price. easy to install comes with all the gear. Best Value for your hard earned money.
