By registering you have begun a mind expanding Google adventure.
If you take the time to explore, a new world will unfold in front of you.
Having said that, my favorite use in my car is to connect my N10 headphone jack to my radio and use the best navigation system available today, Google maps/navigation, and the built in GPS to give me spoken turn by turn directions. The Android OS with multitasking allows me to play my favorite music while using navigation. It even turns the music volume down when announcing the next turn.
You are lucky. I just wish my car had built in Bluetooth so I didn't have to see extra cables!
Hopefully you didn't just waist dealer sticker price of $$$$$ for factory gps in your new car ;-(
