Your guess is correct I ment to say AM...
I did and yes it is possible manually scen ..but even I fix sertain station ( let say 740 AM ) it does not give me any sound ( some distortion shshshsh...)
I also tryed several of them ( different stations ) there is no positive results.
I can not fix station in the memory ,at sertain number ..like we all do programming 6 offered buttons.
FM is ok , CD original changer- ok, aux is funcional.
P.S. I played with sensitivity buttons , but not shure if it was by the rules and right way (unsucsessfull..)
thank you for comm..nt
