Retrofitting traction control, downhill assist......

[pmguanco@gmail.com]

Hello all, Thanks for accepting me to the group! I'm from the Philippines and I own a 2019 4x4 manual transmission Hilux. I believe this topic has not been addressed yet. Here in The Philippines, our Hilux doesn't come with some features that are already standard in other countries ( rear camera, cruise control, downhill assist, traction control, hill start assist.) But next year's release of Hilux here will already include traction and stability control, hill start assist and downhill assist as standard. Surely parts will also become available here as well. My question is, will It be possible to retrofit those things to my 2019 Hilux? If yes, What additional hardware would be needed for the retrofit? Your they need additional sensors?Thanks!
