Had a search and couldn't find any reference to retrofitting the memory and switching to the front passenger seat. Anyone know if this is possible?

I would like to do this too.

there have been some fairly negative posts previous due to restrictions of the system controlling the memory and linking to the keys etc.

however, just the seat having its own memory positions would be fine for me, independent of the car system.

Would require some kind of programmable module and relays. perhaps a raspberry pie?

It must be possible the cars from the EU have memory seat on the left

but not both?

swapping from right to left would be quite straightforward
