Change from manual seat control to electric

[Grb33]

Initially, I was only supposed to drive the car, so I didn't care about the memory of the seats. After a few rounds of Avensis, my wife said that if not for tight parking lots and outside the city center, she can also ride it sometimes 🙂 Changing the position of the chair and mirrors becomes a bit of a chore every time.

In the Avensis station wagon from the end of 2016 (probably the last lilft) what is the matter with adding the memory of the driver's seat and side mirror settings? I can buy an electric driver's seat from this model for less than 60£ (the cover is already poor quality and I only want to change the electronics control because I have leather with Alcantara). Just buy memory buttons on the door and that's it? Do I need to program something or buy a separate module?
