I just bought a USED 2000 Honda Accord EX V6 4 Door sedan used. I am unable to recieve ANY FM or AM radio singnals. I search but NOTHING tunes in. I even tune into local stations that i know have strong signals and the "ST" indicator barely comes on.Any thoughts on why this is? Any information would be greatly apprecited!*Please note that this system is the ORIGINAL Honda factory installed FM/AM Single CD Player that came with the car when it was originally purchased. Additionally, I do not see an antenna on the car itself. So I assume that the antenna is internal.
