I recently installed a D3 in my buddies tahoe. I installed the bluetooth handsfree and i can't get any phone to pair with the radio. I tried my blackberry bold and his Iphone. Keeps telling me wrong PIN. I tried 0000, 1111, 1234. The install manual says to use 0000. Any help would be greatly appreciated. I know the box is installed correctly and used to work in a different car. Thanks.
