I had a cellular cradle installed in the car many moons ago...I no longer use the cell phone anymore as the cradle does not fit my new phone. I removed the side panels and found 2 wires conencted to the cradle. I did the stupid thing and just cut both the wires and tucked them back in and replaced the side panels on the centre console. After doing that I no longer have FM reception. Are the cell phone cradles wired into the FM antenna?...and if so, how can I fix the radio. Any help is much appreciated. Thanks.
