I have now owned 4 Atoto radios, and quite frankly this is the best that I have owned by far. There is virtually no start up lag (old unit used to take a few minutes to start up), the audio quality is awsome, and the feature set is incredible. The only downside I have so far is that the aux port is missing. It seems like they replaced the aux 1/8 inch pin input (which I used on my old unit to input the signal from my satellite radio) with the 4g cellular connector. Bluetooth works perfectly, BUT I have to switch between bt audio from my phone and bt audio from the satellite radio. Not the end of the world, but less convenient/automatic when i used to be able to have both connections (aux from satellite and bt from my phone. All in all it is a wonderful looking, functional and fast modern Android type head units. Definitely one of their best units

I really like this stereo. Android auto works flawless, the audio is much louder than my last stero. It may take a little bit to get used to the UI, but it's pretty intuitive.Allow some time to install the radio if you want to use the GPS antenna and external microphone.

This is my second ATOTO head unit. I upgraded from the S8. This was a great upgrade choice. The interface is pleasant and VERY FAST. The screen has great clarity, brightness and is very responsive to touch. Just like an android tablet you have an amazing amount of customization that you can do. The sound quality is amazing. It even came with a sim card that has a 10 day trial period so you can try out the cellular capability instead of having to use the bluetooth or wifi tethering / hotspot on your phone. This unit is very thin so it provides ample room for all of the wiring behind the unit. It even comes with a built in fan to keep it all running cool.

Just upgraded from the Atoto a6 pro to this unit. This unit is so much faster than the a6 a very welcomed upgrade. I can jump in and out of apps fast with little to no lag something you could not do with the a6. Both radios are 7” touch screens but this one is a tad bit smaller than the a6 had to buy side mounds to fill in the gaps. The sound quality of this unit vs the a6 is WAY better and louder and my subs are louder having to turn the bass knob down more than normal. Screen looks great hopefully we can get some updates for the themes though. I’m not a fan of the themes at all what you see is what you get the widgets are not live. You can assign what app they open when you tap one but that’s it. Can’t change the layout of the themes or make your own theme. But I got this for CarPlay a must have in my opinion. Easy install but I had to purchase a plug from my cars harness to this radios plug the a6 was different. I would recommend this one.
