Hi Khagalin, welcome to the forum.
Do you have the UConnect system with the mirror mic/controls or the earlier one with the controls like below?
If you have the mirror one you will be asked to say a four-digit pin number which you will later need to enter into your cellular phone. You can enter any four-digit pin number. You will not need to remember this pin number after the initial pairing process.
If you have the one like mine in the picture above, the pin should be 0000.
I hope this helps, Tim.
