I believe you might have the glitch when the car setup didn't work perfectly the first time, usually due to a spotty connection. Is it asking you to login every time you start the car and other small glitches?
A factory reset will fix this. I forget which screen exactly, but somewhere in settings you can do a "Factory Reset". It takes about 5-10 minutes to do the reset & setup. You will lose any saved settings.
Alternatively, if you're talking about having to enter a PIN code every time you start vehicle then it could just be that you have to disable "Access Protection" to "No Access Protection".
