The Sony XAV-AX5500 is a great Apple CarPlay and Android Auto unit to be considered for the Honda Civic FB. The only downside is that the Civic FB steering controls run on canbus, so the canbus steering wheel control interface is needed to retain the controls.
Overall, we think the fitment on the FB is pretty sweet and would definitely recommend it to anyone.
The Blaupunkt RC TY camera is also great for those who prefer the OEM look, but mind you a hole needs to be drilled to mount this.
