Electric memory seat install/ USB port

[dantesacco]

Hey everyone, I was just wondering if it is possible to retrofit electric, memory seats in my 1er. Its a 2008 M-sport 125i with electric folding mirrors. Also, in future, im intending on installing an android head unit into my 1er and i was wondering if anyone has done a blank button delete and installed a USB port in place of a blank button.

I've attached some pics of my current set up.

Any help is very much appreciated <3
Cheers.
