im trying to find out how to set up my bluetooth to my phone
When Bluetooth devices blink they are pairing with another device.
Put your car in the pairing mode, and then turn on Bluetooth on the Nexus One
The default pairing code is 0000
Pairing
Unfortunately, you can't change the Bluetooth pairing code on this phone, because it is hard wired to the code '0000'. You will somehow need to change your device's code to '0000' in order for the Bluetooth pairing process to work.

Go into settings. The should be an function that is Bluetooth. Turn it on. Make sure your headphones are charged and when they are you need to pair them to the Bluetooth function. Make sure you are on Bluetooth, turn on the headphones, and the power light should start to blink. Your tablet will tell you it is searching for the Bluetooth and then tell you it is pairing. A number may come up and to finish pairing you input the number. The headphones should show up in the Bluetooth settings as paired. You may have to do this procedure one or two times before pairing is complete. Not all items pair the first time.
When you are connecting your Bluetooth devise, make sure that you have activated the pairing feature on both your phone and your car. Once you in a pairing state, you enter the pin code in the required field.
for my jag it's 1313... give that a try
Following the pairing instructions for the device, iPad, and phone.
Their is no disadvantage in having Bluetooth in car. But you have to take care that if an unknown device ask you to pairing with your car Bluetooth system then you do not need to pair that unknown device as it may send absurd files and may damage your car audio system. So, take care while pairing.
