it has been discussed, the pre 2018 9.2" uses a windows CE platform, the 8" and 9.2" 2018 forward use a Linux based platform.
the issue is the windows CE platform cannot run
CarPlay or
Android Auto. no support for that OS backbone to run those apps.
While I am sure it is entirely possible to flip the firmware from Windows CE to Linux in the older DH models, it boils down to cost effectiveness for the R&D to do so, it would likely require re-writing a lot of code and/or changing out the joined parts like the AMP as noted earlier in the thread, because those connected parts are running of some similar base code to the HU so they can talk.
and there is zero reason for Hyundai, or any manufacturer to put R&D money into a 4 year old model for a creature comfort like
CarPlay or
Android Auto, the logic here is if you want it buy a newer car.
R&D on vehicles is 4-5 years out from the current year, that means the technology when compared to the rest of the world is several years old when it hits the market, as it takes that long to get the car through the process of R&D, testing, and regulatory approvals.
obviously, based on this thread, the newer HU works in an older car insofar as booting up and being functional, but the other things attached to it have issues.
now with enough time and money, I am sure someone can get it to work, either with an OEM amp, and whatever modifications to the wire harness might be needed, or simply bypassing the OEM amp all together and using some type of DSP or LOC sound processor unit piped into an
aftermarket amp.
