What functions did you lose? I would really like to put an aftermarket radio and get carplay. I looked on the iDatalink website and from what it looks like it only supports the prefacelift steering wheel controls.
Never mind, I googled it.
So you have the parking assist buttons and a multifunction D pad above them?
With another button labeled “trip”?
Since when did Corolla offer a heated steering wheel?!?
And I claim to be an enthusiast! Geez
Anyways, all my buttons (2014 LE) are reprogrammable. I even had options for the park assist, that wasn’t even available in 2014. Same goes for the radio.
Find me on YouTube by name, I made more crappy videos. But 3 on the Kenwood.
Also, you can shoot iDatalink an email, I’m sure they would give you the answer.
