Has anyone come up with a way to keep the heat/seat warmer sand radio on while the drivers steps out for say a cup of coffee or to get takeout and the passenger in front seat stays? As winter approaches the keeping of the door cracked open is becoming unacceptable especially when that passenger is the significant other who is very sensitive to cold drafts... She even carries the second fob, but that doesn't seem to help. As soon as my butt leaves the drivers seat and door is closed, Total power down.
