Got this unit for my son Prius C 2014. Since I don’t want to cut wires, I ordered a Prius wiring harness. The Prius has no BU camera so we also ordered one to complete our install. The unit was an ATOTO A5. I was very impressed by the quality of the unit I received. The installation went flawlessly and all was plug and play. There where a good set of instruction (online) all manuals you can need are there. BU camera installation is most of the job (wiring from the back to the front) and take the most of the installation time. Once installed we put the unit to test.Wifi: connect instantly and keep the connection to my house wifi at 50 feet from the parking. Also, once the wifi is connected, you can update the unit software and firmware right there. 10/10Bluetooth: Easy setup and very good connection, phone, android auto, waze and many other applications worked very well. 10/10BU camera: I must say this is a success, definition is very high and clear.Screen: no issue with lag and touch screen responsiveness, surprising especially at the low price they sell this unit.  Don’t wear polarized sunglasses however, you will see nothing. 10/10.Sound: I keep that one for the end because what this small unit can do with the old Prius oem speaker is unbelievable. The sound is absolutely fantastic, specially with the demo music that is already on the unit. 10/10My installation is not completed yet, I wait for the Metra 95-8239B Double DIN Dash Installation Kit to complete and gave a professional look to the job. We are very satisfied and will not hesitate to do business again with Atoto.

Really nice unit, install was easy and fairly straight forward. My only gripe is that I would prefer a volume knob over buttons personally.

True form and perfect fit to replace my old stereo. Screen is bright and CarPlay works very well without lag or delay.

A5LG2A7T is the model this review is concerning.Installation was pretty straight forward. Unit functions as it should (as advertised) out of the box.Software is a bit glitchy and clunky, pairing bluetooth items for things other than audio or phone has proven to be difficult. The wireless android auto forces starts on anything in its vicinity and I haven't figured out how to deal with that yet. Android auto audio skips out sometimes.The home button is sticky. Probably a one off issue.Despite the negative things stated above, for 200 bucks this unit is far above anything else in this price range. Audio output is very acceptable and tuneable with an equalizer app that is very adjustable.

A very good radio at a low price.Installation was very easy. Simply plug in the cables and off you go. There is also an adapter on the aerial cable so that it fits in any case, regardless of how much space there is in the radio slot.The rotary knob is very sturdy. I once had the problem with another radio that the knob seemed very loose and often didn't react when I turned it. This is different with this radio. The knob works very reliably. Another good thing is that the radio restarts every time the car is started. It then takes a little while until it is ready, but there are no connection or function problems. I had to restart my old radio manually every time to get it to work. With this radio, I have had no problems with the wireless connection to my iPhone. Everything works perfectly.The reception of the integrated radio is also great, which has not been the case with other radios.All in all, a top radio at a really low price. I absolutely recommend it.
