It's basically the ways I said above and in your thread.
Those are your options if you're dead set on keeping the RNS-E in the car.
You can either "DIY" this with a Raspberry Pi (I linked you some threads in your other thread); or you can buy something like the Navinc unit mentioned here. The former choice requires a lot more skill, tinkiering, effort, and time and still requires some $$ spent...and there's not even really a certainty you'll get it all working the way you want since there's no "great established formula" at the moment for getting it done. The other problem is updates on the AA or CP side can render whatever you setup, "broken", and then require fixes on the Pi software side to address or workaround.
The latter choice is far more "plug and play" or turn key, but requires a relatively large amount of money spent. It really isn't worth it compared to what else you could buy (aftermarket) with that money. 700 GBP is not really anything to shake a stick at,
just to have AA/CP. But you're free to do as you wish with your money of course.
For AA at least there is not even any longer the idea of "just mirroring your phone screen" because AA is no longer usable as a stand-alone app on a phone. (Note: I'm not sure about CP.) But, even then when you could have done that with AA, IIRC using AA on a phone (standalone) I
think it was limited to portrait view, which would be pointless to see on the RNS-E screen--it'd either have to be sideways or a narrow "strip" on the screen of the RNS.
I suppose as a final option you
could just go with a mirroring (as mentioned in the post you quoted). You could do this with phone screen in landscape mode but you wouldn't be able to get AA like that (again I have no idea about CP). You could use things like Waze and whatever app(s) that way in a "view only" fashion on the RNS screen. You'd still need a phone that's capable of outputting HDMI over USB (many higher end ones can, but many lesser phones cannot); and still need to then convert that to VGA,
and then from VGA (RGB-HV) to RGB-S to input to the RNS-E. This is basically "half the job" of the "Rapberry Pi way", since you're still doing all the video input stuff just not having to deal with any of the Pi code/setup/hardware. But again you'd not get AA nor any way to control anything on the car side without a Pi in the equation.
TBH I get the feeling that you're looking for some "easy plug in way" to do this because you wouldn't be up to doing things like setting up a Pi and doing the wiring, etc... That's fine but hopefully we can be clear here...
Something "cheap and easy" like that doesn't exist for the RNS-E, period. Unless you want to spend a lot for that NavInc module of course...which is not cheap. If you want to do that,
there's your way:

Go there and call them up and call it a day; though a word of caution that thing
might only work on 192s, if you have a 193 you should be sure about it when you contact them--needs to either work with 193 or they have a different version for it. Otherwise it's gonna be the hard way or just go aftermarket. Hopefully this answers this for you because there's honestly not much else to say about it. You can keep finding other threads to ask on but there's not going to be any other answer.
). However the rest of what armran did there is hardware mods--he installed a touchscreen on it and then further installed a CarPC which presumably displays via VIM through the RNS-E and controls by what I'd imagine is a USB interface to the touchscreen.
