I have a 2011 Escape XLT that I just bought Thursday night. It does not have Sync however. I would really like to have Sync or bluetooth for my phone, but don't want to go through the hassle of replacing the factory radio. Is there a way to add bluetooth to the factory radio since it does have the phone button on the dash (not on the steering wheel though), without having to use separate bluetooth unit that uses the an empty FM radio station?
