LF (2015-2019) Sonata/i45
For 5 years I would start my Sonata via the BLink app on my phone. (Push button start, no key)
Unlock drivers door with fob, get in, step on brake pedal, Dash would fire up, H/C & A/C would resume previous state as would the radio.
Turning off car from inside, the radio/media player would stay...
