Hey guys, I am a total nOOb in this, but hey, we all started somewhere right? 
 
 
Well. here's my problem.  I got a JVC headunit and installed everything and it was working perfectly.  Then I decided to uninstalled it again, just for fun, but when i plugged everything again, it turns on fine, and i can play cd's too, but for some reason the radio won't work.  I really have no idea what's the problem

.  Can anybody offer some advice??
Thanks in advance!
