I get FM reception, but not AM...what gives?
I just bought this one-owner car. It's a 2009 xc70. When I try to get AM radio, all the
numbers show up, but absolutely no sound, not even static. FM is OK with great sound
quality. I could not find anything in the owner's manual. Help?
Broken antenna or antenna cable, AM uses the mast and the small center cable, FM uses the outside of the cable and the car itself for reception.
The am transistor is probably bad in the stereo,if it play,s fm good.
Tinnisshoe woud,nt he get static and or sound threw stereo even if bad antenna,?Dunno ??
It depends on the radio, if the PLL doesn't see a connection it might not complete the connection in the output transistors so the finals won't activate. Some of the cheaper units will have static up the wazoo.
Yes,am usually doe,s.
This is a well known and almost common problem of Volvos of that vintage. Search the web for further details. The problem is in the AM section of your audio unit and to fix it will require that the whole unit gets removed and replaced. Unless you're under warranty, expect a bill approaching $1,000 usd.
