I purchased the system directly from the T'EYES's webpage, with the accessories package listed below, including the front camera\DVR and the rear camera. In fact, the only option I didn't purchase (yet) is the 360 camera system. The system was quickly delivered (about a week time) to my chosen pickup place in my home town in Israel. I used the help of local professional to install it. The system fits in exactly the same volume used by the stock system. Right from the get go, the system seemed to operate fine, however, operating some of its rich feature set required bit of support from T'EYES customer support, mostly because the the Israeli Toyota Corolla configuration is somewhat different than comparable US model. That said, all these issues were satisfactorily and quickly resolved with the T'EYES excellent customer support team (we communicated back and forth by email).
As for the quality of the system, it's more than I expected. There's really no comparison with the original Toyota stock system. To begin with, its very quick and nimble to operate, almost like a high end mobile phone. Then, the system is up and running within 1-2 second of energizing the vehicle.
The first thing I've noticed is the improved sound quality of my car. Apparently, T'EYES drivers are much better than Toyota's. The image of the rear view camera is a step function improvement compared with the car's stock camera, and so is the of the Front camera\DVR . The DVR comes with ADAS capabilities, these could be useful for many customers, however, I found them bit annoying to my taste, but I was able to tame them to my liking using the DVR app's ADAS settings.
Android Auto is seamlessly integrated, I can navigate with any supporting app, including Google Maps and Waze, while listening to my favorite music on YT music. Google maps had no issues, However, I experienced some un expected issues with Waze (I believe these issues are purely on Waze court).
T'EYES capabilities goes beyond Android Auto though, for example, I can watch YouTube or Amazon Prime video on the whole 10'' screen (which has an excellent quality) or split the screen with any other SW including the navigation apps.
All in all, I highly recommend this system for everyone looking for a high end Android multimedia system.
