As an owner of an older ATOTO A6 radio that I was very happy with, when I got a newer vehicle that needed a stereo upgrade, I went straight to see what newer ATOTO stereos had to offer. I purchased the ATOTO A7 A7G209PKL. Amazon delivered it overnight and I unboxed it installed it the next day. Installation was very straight-forward for someone who has the experience of installing several car stereos over the years; no surprises here. On first boot, I was welcomed by an intuitive dashboard that operates like most other Android devices. It was very simple to find all of the functions and features of the unit. The rear view camera worked with no configuration, and activates nearly instantly when I shift into reverse. Radio quality is good and on par with nearly every other modern stereo. The sound quality of the built in amplifier is excellent. I ran off of it for several days after installation and the built in DSP allows you to really tune the sound output for optimal listening. Over the weekend, I connected the unit to my amplifier and subwoofer, and now it sounds amazing. Overall, I have no complaints about this stereo. I did have one issue during installation and contacted support. They responded promptly with an easy solution for my issue, so I was as impressed with their support as the unit itself. Compared to my old 2018 A6 (which is still operating in my old truck 8 years later), this thing is much faster, with virtually no lag on any interaction, and the screen is beautiful and responsive. I can't speak highly enough of this thing, especially for the price. You'll pay triple to get a stereo with this much functionality from Sony or Pioneer (if they even offer one). I'll be buying more ATOTO products in the future, for sure.

I already had the Atoto A5L 9” head unit and loved it. I have the DVR cam, front cam, rear cam, OBD Torque accessory, and the tire pressure monitoring system. So many things you can add onto these units. Now they are adding in RGB lighting, wireless cameras, interior cameras, LED signs, wireless monitors for the kids, and so much more. This is the third Atoto unit I have had. I just keep upgrading. Had it in for a few days now. With my old eyes the larger 9" screen is great and it is sharp. This continues all the extra pop to my Miata. It fit perfectly in place without blocking anything. The thing with most of these Atoto units are that all the connections are the same, so it was essentially a plug and play upgrade from my other Atoto unit to this one. The screen is perfectly clear, crisp, fast, and smooth, swiping is smooth, video is smooth, and everything loads quick. One of the best parts about this is that it is instant start, no loading, no android screen, nothing. You start the car and it is on, almost instantly. Another plus for me is all the different audio volume options that this unit has, ring volume adjustment, nav voice volume and to mix it with the music. Speaking of music, which is the main purpose of a head unit, it is excellent. I was impressed with the last one and this also does not disappoint. Whatever manufactures say about amperage is always overstated crap. This unit has more than enough power. If I were to crank it all the way up, I would be doing some damage, not only to my ears, but also the speakers. It really rocks and with clarity. It has so many different adjustments for the sound, a crazy large EQ, time delays, and of course the usual balance stuff. Everyone was so impressed with my old unit that I had two other people buy them. Now I am sure some will pull the trigger and upgrade as well since it is so simple. The original install was your typical head unit install which is not as easy as plug and play, but with the right car adapter, it’s not that bad. All those custom fit units, I know I bought one for my wife's Toyota, are crap. I wish I had done an Atoto in her car before and now I will put my old one in there. With most of those, some company makes them and some other company buys and sells them and puts some garbage android skin on them. It sucks. Atoto does their own thing very well. Good luck with any kind of updates with another generic android unit. I think the main thing most people do, is use it with Android auto or Carplay. I have Android and it has connected wirelessly and flawlessly every time. You can have it auto connect, or select to connect, which is nice choice. I don't always want Android auto to launch once it connects, but if you do it will do it quickly when you start the car. I think it is a few seconds to start and maybe another max 10 seconds until Android auto connects and takes over the screen. What else can I say to help you decide. I can’t believe all the things they are packing in these units at the price. Sure, you can buy a major name unit, but you’re paying a lot more for the name and you are getting less functions and no add-ons. It's a great unit from a great company and it does everything they say it does. What else can you ask for?

UPDATE 2 more weeks later: The talksim prepaid sim card worked to give me LTE data on t-mobile. The APNs auto populated from the SIM card. And the atoto worked as a wifi hotspot. So, if you are on t-mobile or get a sim that uses t-mobile, then you can get LTE data. It's a wonderful device. I can use android auto. We just did a trip and used carplay with my wife's iPhone. And the kids can connect their tablets over bluetooth to share music. I have the steering wheel controls how I want them on a 2004 silverado. And I have the USB in the glove box with a high capacity thumbdrive with my mp3s. It's kind of amazing what you get for the price point. UPDATE 2 weeks later: I ended up re-ordering this radio after trying some other head units. It's nice and having full android with app store is great. That said, it will NOT WORK WITH AT&T subscriptions. The IMEI says "unsupported device" on AT&T's site. I tried swapping a sim card from a tablet into the atoto and setting up the APNs, but I could only get bars and never data. Further, AT&T flagged that sim and blocked its data. So, I had to call them to get my old tablet unblocked and back on the network. There are preset APNs for T-Mobile and the T-Mobile site says "partially supported." So, T-mobile might work. I'm trying a prepaid SIM card from TalkSim (ASIN B0D73RG84F). I'll keep trying to get the radio on the cellular network. But even in the absence of that data connection, I really like it as a head unit. ORIGINAL REVIEW: I wanted this to work SO SO bad. It's a really nice device. The flaw for me is you cannot add APNs and hence cannot get a cellular data connection. Problem 1: AT&T does not recognize the IMEI as being supported (on website and in a store). That's fine I can use an old or fake IMEI to get a sim card and manually add an APN. That's solvable. Problem 2: The settings are really buggy and the APNs do not persist. I put in an AT&T sim card and got the 4G and bars icons, but without the right APN there is no data. I tried using an AT&T APN from another AT&T tablet and the APN from the AT&T documentation. They would never stay in the settings, even after reboots and various methods of adding. In North America (USA) If you are on T-Mobile there are default configurations in the APN settings. I tried a lot of angles. It will probably work on T-Mobile out of the box. If you have another carrier like AT&T or Verizon that is not in the default APNs list, you will not be able to add the APNs to get a data connection. I worked with Atoto support via there website and they were very responsive within the constraints of timezones. I gave them all the technical details about the bugs and carrier bands. Hopefully, they fix this with a firmware update.
