Problem w/stereo

i installed a Parrot bluetooth system on my car so that when i receive a call

it mutes the radio, i connected everything the way it says, but now i'm only

able to use my radio using the controls on the steering wheel, i cant use any

controls on the radio or near the radio, i even unplugged the parrot system

and connected everything the way it was before i messed with it and i get

the same problem. any suggestions on how to fix this? by the way i think its

a 2005 g35 sedan w/bose system, w/o nav
