Well, the ONLY "modification" I made for the radio (I have an android radio which didn't ever disturb the memory seats evem after having it installed for 1 year) is that I cut the blue wire of the 17 pin loom of the radio for the amp to receive the AUX signal and start when the key is in AUX position, that is a normal 12v wire that only gives the amp the signal to start and I can't imagine how that would disturb the seat memories. Also, as I said, I disconnected the amp completely, left the car more tham half an hour disconnected from the battery, than connected the battery without connecting the amp wiring to the battery, still, memories not working.
Also, when unlocking the door and if the seat is in another position than normally set with the key in the ignition, it doesn't move amymore to it's default position set by me like before, so the lazy seat function is also not working anymore
