P.I.E has completed a prototype interface on the 05 mustang shaker unit to access the "AUX" feature!..There is a writeup on it from a member over at www.allfordmustangs.com.
Here is the link -
AUX button

 

sweet jesus, yes!!!

direct link to photos, etc. here.

 

The unit will be capable of dual inputs as well. Push the AUX button twice!!

SWEEEEEEET

 

Great find.....I have the inline FM modulator. It don't sound bad but I hope the AUX adapter sounds better. So far, I have not seen a price or if it works with the XM Roadie.

 

I would ASSume it will be compatable with any type of audio output from any source!
Looks like it might be a pain in the **** to install, so that will jack the price up for professional installation. But worth it - IMAO.

 

i want one now
