Bro, Congrats on the new purchase.
Just installed 4 point reverse sensor from my friend's shop in Taman Sea. RM485. Good thing about these sensors is they're not as loud as the built-in PDCs. Can be quite irritating at times.
As for changing the player to those aftermarket players, I found a shop that can integrate the player to the multi function steering. I've also ordered a set as they've run of our stock for the moment. If you buy the player from them, the module costs RM350 plus programming. Otherwise, it's RM450. Using infra-red technology, your multi function steering will now work. :top:
They have modules for Japanese cars and modules for Conti cars. So make sure you get the right unit.
