If your screen tells you it's trying to aquire the signal, but you can't tune to channel 0, it seems one of two things.
1) Your antenna may not be connected to the unit in the trunk. Have a look because some peeps have unplugged the antenna to add other sound devices.
2)You unit itself could be bad since it doesn't allow you to tune.
I'd jump into the trunk, remove the trim pieces and have a look at the unit. You'll have to do this to install your new unit anyway. If it's a simple matter of re-attachng the antenna, job done ! If it's already attached, then it would seem your suspicion is correct - the unit has gone titz-up.
Good luck and please post however this project turns out.
