2000 740i dead radio controls, popping speakers!

Hi everyone, nice looking forum. I just bought a 2000 e39 740i with mk2 radio/nav system. When I start the car the nav screen goes straight to the fm radio screen. The speakers make loud popping/hissing noises. All the buttons on the head unit are dead or inop except the volume control which will make the speaker noise louder or quieter when turned. The steering wheel controls will change the radio station (even though the head unit buttons won't) and volume control seems to work as well. When the display says its picking up a station it still just makes humming popping noises. Has anyone ran into this, I'm thinking I need to change the head unit but was hoping someone has ran into this before. Thanks
