Double Din head unit with Android Auto and Apple Carplay for $149. Has USB, Aux, and SD card.
I've just bought and installed this, and I'm impressed with what you get for the price. It's very comparable to the Sony XAV-AX3000 I have in my other car. It's difficult to compare sound quality as the Sony is in a BMW an this is in an old Rodeo, but the features work much the same.
Unit starts up reasonably quickly (not as fast as the Sony, much faster than any of the cheaper android units I've used before). Radio and Apple Carplay work perfectly, the touch screen is pretty responsive too. Physical buttons are pretty plasticy, the volume knob feels solid. The flap that covers the USB just dangles down which is a bit tatty, but otherwise no complaints.
That seems damn good for $149.
