I love my new ATOTO head unit! I installed this into a 2008 Saturn Sky. I bought the CANBUS integration module separately, and with that, I got all of my steering wheel controls to work on the new head unit! The sound is awesome! I had the Mongoose amp factory installed and worked will with this device using the low input RCA jacks.I did have some technical issues with the rear camera that I also bought from ATOTO. I contacted their customer support. They were very responsive and helpful. With a system upgrade, all worked out well!Overall, ATOTO was a fantastic company to work with, and their product is high quality!

This unit is a very significant upgrade from my A5L unit. The additional cpu and memory make this head unit very peppy, indeed. They are really packing in a lot of features and upgrades into their hardware. The native music player supports M4A format which is a good thing for all of the audiophiles out there. They have integrated a DVR into the unit which uses the front and rear cameras (sold separately) and is therefore not dependent on the DVR Cam which is available in their store. When adding additional USB mass storage for my audio it indexed the files pretty quickly. Also, for all of those out there that like their music loud, if you have this unit connected to an external amp then it's pretty impressive.The only thing I would advise people of is that with the rapid release of upgrades to their head units, some of the features and apps need a little smoothing.That being said, their support team is very responsive and helpful.This is my 3rd Atoto head unit and each one is a leap forward from the last. My first unit was an F7, then an A5L, and now the S8 model S8G2A74MS.I would recommend this to anyone out there looking for a good bang for the buck. It keeps my old 1997 Ford Explorer feeling fancy.

This unit was extremely easy to install, the screen Is compact and you have plenty of room to work with, made installation a breeze. It comes with a ton of features and the 4G is a nice feature to have even when you may never really need it, I can see it coming in handy when you least expect it. It booted up super fast and only took a few seconds after connecting via my iPhone cable to setup CarPlay mode. On some Android models this can be an absolute pain and you need to add interfaces, but this is built in to the unit and booted right into CarPlay. If you have steering wheel controls, you might need an interface for that, unless your vehicle has the simple two wire setup. It took me about an hour and a half to install and that was taking my time.If it’s a newer vehicle you may need a CanBus interface. I already have one on my truck so I plugged it in and it worked just fine. For the price you pay I would say it’s worth it, it’s a quick unit and is very easy to use!

I saw mostly good reviews of this unit and tried it out in my truck. The price point great. And it did work well for the first couple of months. But then I started having problem with the Apple CarPlay. It couldn’t fully connect in a way that my phone said that it was connected but nothing happened on the unit. It would get stuck on the “authentication verified” screen and wouldn’t go any further. The only way I found to fix it was to do a full factory reset. I did this 4-5 times in a month before it stopped working to fix the problem. After about another two weeks the radio started going out. It wasn’t getting a poor radio signal because I could see all the station and song info, but nothing came out of the speakers. I took it into my local car stereo place and they said that they have experience several connectivity issues with the Atoto units across the board. The annoying part is that it lasted just long enough to get past the amazon return window. So now I have to purchase a more expensive unit and not get my money back for this problem unit. Do not recommend. Spend your money elsewhere.

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.
