Originally 580, some reported success with 500. Still recommended to use the same spec at 580 or better especially premium and above variant.

Aside from controls, may I know if its compatible with reverse cam, sensors etc? Do you mind to share the TB link? Thanks in advance!

I think it's very normal especially on high speed for a boxier SUV, I am shocked that yours only had it above 160 kmj SUVs are incompatible with aerodynamics, but kacang hasn't been on a Bentayga SUV before, so cannot judge for luxury SUVs

Rewiring

ATLAS and GKUI both fall short due to hardware limitations. It's better to use CarPlay and Android Auto, as they don't compromise internal ROM, RAM or other resources.
