Hi,
I retrofitted Traffic Jam Assist at F39.
At that time, I thought 5AT was essential. . .
My friend F45 is a 5AS equipped car that is not a 5AT.
We recently implemented a 5DF retrofit. Today we are retrofitting Traffic Jam Assist (5AR & Quidzel HOD Emulator).
5AR (Quidzel HOD Emulator) can operate on a car equipped with 5AS + 5DF.
P.S.
"5AS + 5DF" is almost the same as 5AT.
