Ok...Went I turn on my rear defroger on my civic my radio is capting like 3 radio stations ,Went I turn it off it's capting like 10 .This is weird ! What's causing this ??(My head unit is also the stock one for now ).

 

I have a Soney xplod and it does the same thing. The sterio shop that I use says there notorious for that and you cant really do anything about it but I think he is full of s#%$. I think he just didn't know how to fix it so if you get a useful tip let me know.

 

did you tint your back or rear side windows lately? how long has it been doing that? you have a radio booster on the passenger side in the rear under the plastic that follows the rear window. if the ant. wire in there is not plugged in completly, it can get interference by close power, also check if the booster is getting power. I had my windows tinted and had that same problem, so I checked and the ant. wire wasn't pluged in completly.

 

Thanks man ! My radio started to do this when I tinted my windows ..Probly the same problem that you had
