Hello all, so I bit the bullet and will test out 2 devices, and send back the one that doesn't work or works "less good" (perhaps laggy, or some other quality). Both are under $70.
First one is the Carlinkit 4.0. It needs to be the 4.0 because the 5.0 will only do wired carplay to wireless, or wired AA to wireless. The 5.0 will not do wired carplay to wireless AA, so we have to use this older model. This device is ONLY Carplay or AA, it does not have a separate Android option, meaning it is a "2 in 1" solution. I don't really care about the whole separate Android OS as I won't be using it to stream videos while parked or whatever.
Second one is this thing (
https://www.amazon.com/gp/product/B0D91NLXN8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1). This one is a "4 in 1" solution, meaning it also has an Android OS (version 11 only but I don't care) and I believe it can mirror an iphone screen, which I also don't care about. The key is that it still is ONLY wired Carplay as the connection. Most of the modern 2024 quad-core versions of these things will do native wired AA which we don't want for our Rams because we already have a nerfed half-screen version of it. This one has a Qualcomm quad-core CPU which I hope will be better than the Allwinner CPUs that the other ones were using (like the Play2Video versions).
Of all the online images and reviews of these devices I have never seen one show a portrait mode layout like our Rams. So I have no idea how this will go. Maybe it will still only give half a screen, not sure. My phone has latest AA with coolwalk I know for a fact because it worked with tiles on large screens on 2 different Fords we had (Mach E 17" portrait and F150 14" landscape).
