OK, so I waited to feel confident that the stereo works well. I dont like giving one week usage reviews, that that people do that. I have had this for about three months. Second thing that upsets me is, perspective and common sense, use it folks, it doesn't run out. This is a CHEAP stereo, not an 800 dollar Pioneer AVIC-7000NEX. I wasnt looking to get the same quality and assumed I wouldn't. However I feel I made out, since this unit fulfills my needs and options I wanted. I installed this unit myself, I have done it before and KNOW what i am doing. Most OE stereos have a diagram of the colors, just match them up. Im not a stickler for soldering, I just twisted and used heat shrink from Harbor freight, no problems in 3 months.I've driven for up to 8 hours continuously and not a problem, that it might overheat. Love the fact that I can plug in a 64gb (Limited to 64) USB drive and play a mix of music or movies. Movies do have to be mp4s, have not tested other formats. Just use Handbrake to convert. Sound quality about the same as my OE Honda stereo, which I enjoyed. Not an Audiophile so I wont speak for you. I've cranked it and it doesn't distort until the very limit, just like the Honda OE. I've read people on other cheap stereos reviews complain about static, I didn't have any issues. This was installed on a 2008 Honda Civic EX. While I have installed radios before, I have not installed these in dash screen ones before and recommend you watch a few video of your particular make.Pro:Quality is decent, again not top of the line. My friends thought it cost way more.Bluetooth is good, works well. Some people expect the sky. it connect and sound is good. It comes with a mic that I placed in front of the steering wheel. I don't recommend it or any other cheap unit, if this is your main objective to use hands free. Screen it small and depending on your car and the glare during the day, you will be fumbling around. I have an android and just swipe on the phone. I don't get too many, maybe 6 a day and not problems.GPS was my main objective honestly. From a light user perspective. While it was at the top of my list, I knew the maps would be kinda of sucky looking. They were, but very readable and good turn by turn directions and menu options. Shopping, gas, food and other location points show up, or turn that option off. If I have to rate it 0-10 Id give it a solid 7 for usefulness. I use it about 2 times a month for really long trips.Screen doesn't scratch easily. Some mentioned scratching on the screen with other units in this price range. I just use my fingers and no scratches. very happy about that. Placed the the GPS under the dash, its magnetic, on top of a steel tube and its works fine.Backup camera, was not part of the package. That was my second want. I bought a Pyle plate camera, it was easy enough, if you aren't scared of making a hole in your car. It work well for me. I placed a switch so I can use it when I am driving, just did. Never have though and might set it up again to use the reverse.Sound Quality is good on Movies, Music and Stereo modes. If you are an Audiophile get the Pioneer.Cons:Glare, I expected the glare, almost cant see it during the day if its inclined upwards a bit, like mine. At night it its fine, it doesn't have auto brightness adjust when you turn on your lights. It does have three brightness modes, and it is very bright at night, even on low.Response, menu can be a bit slow. Remember, this is not your Galaxy S9. Iphone users might be too demanding for this unit.Fit, not the Stereo or manufacturers fault. It comes with a small bezel. I wanted to point it out for those who complain this is all you get. If you want a more professional look Id have it done professionally, and two Id get the Pioneer if you a High quality buff.USB Format has to be exFAT if its over 32 gigs. Not in the instructions. HTFS and FAT32 seem to work fine with 32gig drives. I bought a Scandisk tiny 64 gigs USB for this. I have a few movies and a lot of music.I bought the kit for this unit with the speaker and power adapter cables, which made it a cake to install. The in dash was actually better that I thought it would be. I recommend you do your homework and watch some videos of other units installed for your make and model.Over all I am happy. I would rate it a10 out of 10 for the price. If it were the Sony Id give it a solid 5, and return it.If you are getting a cheap radio for your car, I recommend you decide what your top options are. There are cheaper units. This had everything I wanted. Some might not want the GPS or the backup camera is not important. At this price, I found nothing. Pics at night. For a another 50 or so I could have gotten a similar unit I suppose. I do recommend it based on my experience with this unit. Your mileage may vary. Best of luck.
