This classic Land Rover Defender 90 came to us for a head unit upgrade and backup camera. Due to the single din radio design on these older Defenders (late model Defender 90/110 had room for double dins), we were limited as far as what units we could install. Our customer wanted something that could do Apple CarPlay, Android Auto, and display a backup camera. While we do have small single din units with LCD screens (3.5") that can display a backup camera, they are a bit small and don't offer such a great view. Also, due to the dash and radio mounting angle, traditional flipout radios would not really fit and would hit the upper dash trim.
This Sony XAV-AX8000 head unit offers an incredible 9" display which makes parking a breeze. It's also got a bit of extra adjustment which let us angle it far out enough that it wasn't smashing against the dash. That being said, due to the diesel engine in this Defender 90, there was significant vibration which does make viewing the screen a little difficult at times. We installed a compact bullet type camera on the rear bumper just below the spare tire.
