It always defaults to the last input you had it on. So if it was on SD card then it will be on SD when you start the car again.

I just hooked up the handbrake line properly, IDK why people go out of their way to enable dangerous situations. But it is not required for operation. My SPH-DA120 used to set the clock from the GPS' time signal, which helped a lot with accuracy, since it was constantly being updated. But my W4400 does not. They expect you to set the clock manually, which is annoying. The car should be sending its GPS location to the phone, which would help save battery during wireless mode, since the phone won't have to power its own GPS module, although it probably does for redundancy reasons anyway. But I find that driving around downtown, the signal was much better for CarPlay once I hooked up my GPS antenna. You can forgo it, but is it really worth it to watch a movie while driving? Also, if the insurance companies find out that you have a bypass, they could cancel your coverage. They like to find literally any reason to deny coverage. So when, not if, you get into an accident while watching a movie, you better take the bypass out.

I have a iPhone 8 Plus and it auto connects every time. Some phones put the bluetooth module in to power saving mode, so maybe turn that off in the Android settings. You need both WiFi and Bluetooth enabled to do wireless CarPlay, I'd presume it's the same for Android Auto.

I had a SPH-DA120, but the touchscreen delaminated and made it look like garbage, so I bought a 5201NEX, but the internal SD card died within a week of using the navigation so I returned it. Now I have a W4400NEX but for some reason this one doesn't use the GPS' signal for a clock sync? Seems annoying that I have to set it manually, mostly because radios always desync from the actual time, and I figured having it use the GPS signal for time would keep it accurate. Is there a way to have it use the GPS' signal for time? If not, I don't even see a reason to plug it in, since this unit doesn't have navigation...
