Just purchased a used 2015 KIA Optima SXL wanting to customize the screen when I turn on the car to play a different animation from the stock KIA logo is that a thing or not possible through the stock head unit? I know how to access the engineering mode but some of the menus are in Korean.. can I plug in a USB flash drive, upload a gif or MP4 video, and be able to set it as the animation that comes on when I start the car? I’ve seen it done on a bunch of different makes just not this car. Also if anyone knows how to change the chime to set is as your own mp3 that’d be super cool too. Thanks it’d be a great help.
