Incredible and a Iphone ready radio

[mattress74]

I have a IPOD/Iphone ready radio in my Harley. The radio has a rear USB port and my Iphone could be plugged in there and then can be controlled from the radio head unit to listen to all my music while charging the battery. Is there a APP for the incredible that will "trick" my radio into thinking its a ipod/Iphone so that I can listen to and control the music player from the head unit while charging the battery? If not a APP is there another way? While riding my bike I do not have a way to control or change the music player from the phone itself due to obvious safety reasons so I need that control from the head unit.
My radio is a JVC KD-R900.
Thank you for any help...
