A solution
I got a solution from xda-developers.com
The Peripheral Electronics Media Gateway PXAMG GM5 Peripheral Electronics iPod Vehicle Adapter is compatible with the 2005 Ford Mustang factory radio. The adapter connects the iPod directly to the vehicle's stereo system with CD Quality Sound, Power and Charging, as well as text and track control on the factory radio. By adding the HDRT you can also receive HD radio stations that can not be heard with a standard FM tuner.
