I think this is the right forum to ask in, I apologise if it's not. This is something I theoretically can suss out for myself, but I don't want to reinvent the wheel and I also don't know what the best solutions for the UK are, as many results when searching are American focused.
One of the most exciting things about getting the Range Rover was the presence of a fabricated metal bar on the dashboard for a ram mount... nah, just kidding, but I was pretty pleased because a couple of years ago I was testing 4x4s and got a Garmin Overlander to review. This device is huge, so when shoved into the windscreen of a current Wrangler, Hilux or whatever it served less as a map, and more as an obstruction. On top of that despite having a tethered WiFI connection and a web browser, the sodding thing wouldn't log in to TW2 - ultimately it was no more useful than a regular satnav apart from adding some dials for altitude, pitch and yaw.
So of course it's spent of the time sat in a box while I wonder what the hell to do with it. Then I got Desmond and have a Range Rover that's basically made of added-on dials, screens and brackets. The Overlander fits very well on a ram ball mount I was given, and doesn't obstruct or obscure anything. Still useless as a means of finding BOATs but meh. I thought I'd finish the review, and get some tips and details up and some nice pics of it in a 4x4 that actually could benefit from it rather than a modern thing with CarPlay/Android Auto and a larger, sharper screen already provided.
Except it only supports one kind of reversing camera (discontinued), is still not terribly useful for navigation compared with a phone, and I'm sure I can put something better together.
Is there a rugged Android tablet/Windows tablet or iPad setup that people have found particularly useful and user-friendly as a way of getting TW2/similar off-road navigation, some sort of media control, and accessing reversing camera stuff? Anything which has the necessary sensors and software to replicate the pitch/yaw dials (though I have some analogue ones on the dash I might not keep them if I replace the dash to reduce the number of holes). I have a Panasonic CF-19 and vehicle mount but that's a really bulky and obnoxious setup (it's also quite slow). I was looking at a rugged Windows Mobile phone thing but thought Windows Mobile was pretty much dead as a platform of any relevance for apps, really only suited if I could develop my own app.
Bonus would be if I can use it as a media source and replace the single-DIN CD player with a pure amplifier, just headless media controls and simple, shallow fitting.
