F/M is not working

[ryanx99GS]

With the stock headunit, the F/M radio will not get signal. I checked all the fuses, connectors etc. Restarted the battery, restarted the headunit, put in the code and it still dose not work. A/M works perfectly fine. Anyone have any ideas why my F/M wont get signal?

i know it is a stupid question but did you take the headunit out and check to make sure both antennas are connected?

The antennas are just a split between the glassmount and steel rod. They don't discriminate between AM and FM.
Pull the radio and actually disconnect the harness. Sometimes the processor just "sticks" -I've had them lock into European mode before- and completely powering-down will get them to reset.
Otherwise, either cruise eBay for another, or just pop for something modern that'll deal with MP3s and memory cards.
