I absolutely love everything about my 2015 LR4 HSE with the exception of...the lack of seat memory. My wife is 10" shorter than me and for such an awesome expensive truck, seat memory is a lacking feature. Obviously it was an option and on the LUX but I am curious if anyone knows if it can be added? Are the wires and all required in the door and ready to go (like the tow hitch wiring being nearly all there)? Is this a standard upgrade that others have done?
