I opted to not get the xite so I cannot add a good comparison. But I will let you know I spent a good amount of time weighing the xite option and playing around with it.
In the end, I just got the factory Sony newmar installs. As soon as I got the coach home I already had a Kenwood dnx994s ready to install. It is perfect for what I need it for. It has built in Garmin nav (not RV/truck specific so no low overpass or weight restriction warnings) but I use a Garmin 760lmt for that.
The key feature I like it for is I can plug my iPhone in and use the Kenwood s built in Apple CarPlay for Waze, google maps, pandora, Spotify etc... sound is better too and I can customize the settings a lot better. I also added a Kenwood dashcam that works great and I can add an additional cam if and when I need.
There are lots of options for double din radio replacements. I have done well with Kenwood and pioneers in the past but YMMV as it’s like picking ford Chevy dodge etc.
I also replaced the electrical socket by the ac controls w a dual usb receptacle. It has dual female usb plugs in the back that plugs directly into the usb cables coming from the Kenwood unit. The bottom one is setup to connect my iPhone to CarPlay and the top on is just a charger. I had to enlarge the hole a little but not a big deal and it works great and looks factory.
Sorry for the dark pics.
