In this respect, this adapter is initially acceptable, affordable transitional solution for playing MP3 files with the older Ford radios.
I intend, however, to connect a memory card reader with MP3 function CD changer in the foreseeable future. Something there. Also has its limitations, is a bit more expensive, but also provides better ease of use, for example, with the steering wheel remote control. .... But that's not here ....
This adapter cable here, money is absolutely worth and allows the use of otherwise fallow Aux-input with little effort.
