I am glad to say this portable Wireless CarPlay has been great for the time I have used it about 1 week and it hasnt crashed or disconnected once. Screen is great vibrant and sharp with great touch sensitivity. A quality screen indeed. Functionality will be as good as any CarPlay or auto android but the sound quality via the Aux cable is not very good. Its too tinny and lacks bass or dynamics. FM transmission is much better with punchy sound but you do get the odd radio static sound as its via FM signals. You can play around to choose a frequency that works best in your car. Overall a great device albeit let down with sound quality via aux. I like the back is flat so I can mount my metal plate to magnet holder.

I bought one more to try to put it on my wiff car
I’m completely satisfied.

It seems to be cheap.
