Did another search (I've been checking every month or so) and a seller claiming to actually have RHD fascia has *finally* turned up, so maybe they do exist now!
https://www.aliexpress.com/item/1005006393241869.htmlI've just ordered this to fit my unit, but since it's aliexpress it won't be here for a while!
Definately check with TEYES if their unity will fit RHD, if they claim it'll work for either LHD or RHD though, they're mistaken!
Radio unit from the EX has very different connectors on the unit (I looked into this option before eventually ordering my generic android unit) - attached a picture of what I managed to work out from looking at ebay listings for parts etc, but almost all the connectors seem different
As for installing the TEYES unit, it should mostly be the same as mine (hardware is identical, software will be a bit nicer on the TEYES one over the generic unit) - The dash is a bit of a pain to pull apart to get it in, but not too bad. The unit itself should have adaptors for the existing cables that just connect in, and then for the extra antennas etc it's just a matter of finding somewhere inside of the dash to hide them
If you decide to get the cameras with it, considering getting them fitted professionally, they're a bit of a nightmare to route the wires back to the radio!
Didn't take many pictures of the process to fit it, but the main part is removing the piece of trim below the radio the get to the various screws that hold in the radio - definately get some plastic trim removal tools to help take this off, as it requires a decent bit of force and you don't want to rough up the edges!
