Monsoon radio won't tune at all. Please Help

[sean6361]

Hi, my 99 camaro has a monsoon audio with single CD, and have a problem with the radio. The symptoms are as follows:

1. The radio (am/fm/fm2) does not tune at all, just making white noise.
2. The seek buttom sweeps all the frequency range without picking up any station.
3. The radio has been working perfectly. It just happened yesterday.
4. CD player works normally.
5. Antenna (manual) is still attached.

Anybody knows what is wrong with my radio?
What should I check to fix it?
Please help. Thanks.

Pull the radio out of the dash, check the antenna is still plugged into the headunit.

If not that.. check the ground if there is one on the antenna..

Then still no tune- replace the unit.
