I got this product for free, the following is my honest and unbiased review. (Mar 7 2025)This review is for the Atoto A5 Lite model A5LG2A7T-S22 (2G+32G) unit, which includes a mini OBDII scanner and a backup camera.The OEM stereo in my 2008 Toyota Sienna locks up in hot weather, so I recently replaced it with a 7” Android unit with 2-wire Steering Wheel Controls capability. However when I saw this Atoto model A5L Android 9 Double DIN stereo with 7" touchscreen (2+32GB) with GPS, mini OBDII scanner, and backup camera, I wanted to check it out. The unit comes with wiring harnesses, a backup camera, a mini OBDII scanner, an external GPS antenna, one USB connection cable, sheet metal mounting brackets, and a booklet that directs you to download an on-line manual. No backup camera or external microphone is included, although either one (or both) can easily be added. There is an HDMI socket on the back of the unit however the downloaded manual did not explain what that HDMI socket is for (I assume it's for output). This unit has two Steering Wheel Control (SWC) wires (SWC1 and SWC2), and so with the correct wiring, the unit is able to communicate properly with the SWC buttons on my 2008 Toyota Sienna, no rewiring or 3rd party SWC control box required. I did a bench test of this unit using a 12v power supply and some car speakers. My bench test did not include testing of the backup camera or the OBDII module. This unit has some nice features: *Once connected to your car, the unit starts up quickly. *The user interface is pretty intuitive, and even has multiple User Interface options. *Menu icons on the sub-pages can be re-positioned. *The unit has front panel hardware buttons (much appreciated!) for Power/Mute, Volume Down, Volume Up, Previous, Next and Home/Mic. *The unit has a front panel TF card slot, USB socket, and Aux In jack. *You can tune the AM/FM radio by sliding your finger across the frequency display. *There is one AM and 3 FM “bands” identified as AM1, FM1, FM2, and FM3. You can program 18 FM station presets into each “band”. The unit shows 6 presets at a time, and you can access the others by sliding the row of preset buttons left/right by using your finger. *The “magnifying glass” icon gives a brief audio scan and sample of the 18 presets. *The display dims when the parking lights are turned on. *The unit has a front Micro SD card slot so you can play music, display pictures, or watch movies loaded on that card. You can also store and playback media on the unit itself (which has 32GB of internal memory). *Album art and lyrics (if available) are displayed. *You can play music, and place and answer phone calls via Bluetooth. *Phone numbers that are Blocked by my phone are displayed at the bottom on the unit’s Contact List, out of the way. *You can rename the unit’s Bluetooth name. *There is 48-band (too many bands and too cumbersome in my opinion) DSP equalizer with preset curves plus 3 USER settings, and separate Surround and Loudness settings. *There is a separate subwoofer setting. *There is a section to set time delays and frequency roll-off profiles. *Sound is pretty good. Bass notes hit nicely and highs are present. The overall music sound quality is good for this price range, you can crank up your tunes and enjoy them, without significant distortion. This unit also has some shortcomings: *When the Music or Folder icon is pressed and internal music files are being played, the unit takes the lazy way out and does NOT jump to the folder and show what it Now Playing. Instead, it will show the last screen shot, or jump to display the first (topmost) folder/song, which of course is –not– what is Now Playing. *When listening to music via Bluetooth, you cannot traverse folders (a shortcoming also shared by other units). *The Contacts listed on the unit from your phone are displayed in 3 columns, and so only 10 characters of each contact (too few) are displayed. *There is no way to Search for a contact, you must display and browse them (time consuming and distracting). *I was not able to read a USB drive with this unit. I tried the cable USB as well as the USB socket on the front panel.My primary reason for a car stereo is for listening to FM stations and playback of my own MP3 music files, with Bluetooth phone capability second, and Bluetooth music third. And unfortunately listening to my own MP3 files (stored in folders on a USB memory stick) is where this unit falls short. For me, the following is a significant shortcoming: there is no Play All mode! With this unit, when browsing by folder, music playback is limited to that folder. You can’t simply press “Next” to go to a new folder, instead you have to manually choose a different folder. And if you want to go to the Next folder, first you have to display the current folder! There is no way to play everything on your TF card (or USB memory stick) in folder order. Instead, the unit reads then sorts ALL of your songs from ALL of your folders and p...
