Fingerprint Start button retrofit

[mannyo]

The fingerprint reader in my D3 is about the only thing I've never had a problem with (now tempting fate).

When the car has been driven using the key in the ignition by another driver, and all setting altered, I just jump in press the button and go. A/C settings change, Radio changes, my contact list pops up, seats/mirrors and steering wheel adjusts itself.

Jeez, Apple can't even get it right 10 years later! I turned the 'feature' off on my iPhone 5S a couple of days after buying it.....

The iPhone (much like many laptop options) needs a swipe, where the A8 one is a full finger pad read, but is really easily affected by angle, and pressure used.

My wife always gets in and starts the car in the morning and does the preflight checks such as heated seats and windows and entering destination.
I would hate the seats and everything to move to her position. The memory positions are stored with the Key ID at the moment would this be totally redundant if Fingerprint ID is fitted?

It would, yes... Assuming the thing works every time.. Car will always start if it can find the key as the fingerprint is user ID only, not security.

...so where all this info would be stored if key is redundant after fitting fingerprint switch???

The key ID is not redundant with fingerprint sensor... the seat position etc. will be still adjusted based on the key ID. For the same reason I find the fingerprint sensor a bit pointless though
