A:AnswerNot on the Apple CarPlay screen, you can only choose the available wallpapers in Settings. But on the main JVC Home Screen you can, but it’s a difficult process. I’ve attached the photo of how to do it.
A:AnswerYes, should not be a problem. If having difficulties could always load a virtual app such as google or microsoft launchers. The deck is initially designed for mac os though, so you should be fine. Android however, it doesn't like at all unless streaming as purely media device.
A:AnswerFrom what I've seen, you would be better off with a single din setup. In order to install a dDdin system you would have to either cut out part of the dash or get a much more involved install kit. It will however work, it would just possibly take a little more planning and research. If you are willing to go that far however, I would reccomend a higher grade deck in the first place.
A:AnswerIt should. They make dash kits (that need to be ordered for an extra charge), for all makes & models to make them fit and look awesome in any vehicle...
