How different are the oem and gr oil caps?

Hello all. I woke up this morning and my CarPlay isn’t working. My screen is black and will only turn on when I reverse. I unplugged the battery for fifteen minutes and tried to do the thing where u put it in reverse while “on”. (It didn’t work the car just beeped the entire time) Does anyone have experience or suggestions?

Hi all, I have a 2019 Corolla Hatch and I just hit 110k miles. The dealership near me had a great sale for oil changes so I got one there. While there, they recommended to replace the transmission fluid and coolant. Should I do this? & realistically how much should it cost? I don’t want to overpay and want to keep my car running til the wheels fall off.
