Hello, I have 1 personal iphone 4s and 1 work iphone 4. Can someone tell me how to pair both phones onto the radio? I have a c2. When i go to BT pairing it asks me if i want to delete all devices (if i press NO, it doesn't do anything.) If I press YES, i can only pair one of the phones and the other one will say "make sure BT is on and device is in range" or something like that. I would like to pair both if possible (for safety reasons when driving and getting a phone call). Any help will be appreciated! thanks!!
