P.I.E. has finally released an auxilliary input converter for the latest generation of Ford stereos.......which does include the 2005 and later Mustangs. Logjam Electronics is not selling them for $89.95. FINALLY, us satellite radio and IPod users can hardwire our devices to the stereo. The link to the part is listed below. http://www.logjamelectronics.com/piefrd04aux.html There is some bad news though. Apparently there is a firmware issue with the chipset used in this device........and it affects the use of this interface in the Mustangs. They have identified the problem, but have not received any of the corrected interfaces. There is a work around though. So if you absolutely need one now, they will work. If you can wait a little longer, the "fixed" ones should be arriving soon.
