I wonder if anybody else here has had a similar issue... I have retro-fitted a bluetooth with usb module to my 09 fiesta (with the kind help of iNath) and can now play my music from my iphone or usb stick through the car stereo with full control through the steering wheel. The only drawback, despite having the most recent update from Ford, is that while i can stream music from my phone via bluetooth I can't control it through the stereo or steering wheel controls!? (iphone 4 running most recent iOS6)
Any body have any ideas?
