Previously, the person sent me an entire steering leather wrapped with both side controls and also telephone (answer / Cancel / Bluetooth) buttons on the left under side.
Cruise control as far as i searched doesn't work in this car so i didn't bother using them. Some how my installer was a noob and he said the buttons don't work. (one can use those buttons for other audio controls thou.
Later i got single side buttons blank and Silver trim, So i installed these.
The installer later realized Suzuki and Toyota buttons work differently then Honda and he accepted his mistake.
No alteration as such, You just need a multimedia spiral cable (charkhi) mostly people retro fit Toyota Charkhi (grips are same the hole needs to be filled a bit), I managed to get a Suzuki Charkhi but it was broken to fit, Later we agreed upon using the Toyota Charkhi fortunately airbag wire was grip to grip (else a toyota charkhi might need airbag wire cuting (my orignal charkhi is with me)
Some wires need splicing to make the multimedia inlet work rest is grip to grip.
