It's not only the remote start, it's every time I get in the car the temp is set at 71°f. I do know there has been a few times that it did save the temp but I don't believe overnight. There's a delay for the temp controls to be active once the car starts.
Also,
On my 7862 i turned on START/STOP so when I was parked watching a movie waiting for my wife to go shopping, the acc would be on & when i would start the car, the radio would stay on and the screen would not turn off and reboot. I can't seem to get this 7870 to function the same way. If I attempt to start it after sitting, it shuts off & reboots. Can I bypass this also?
