No sound from anything but FM

check your antenna

You may have many different issues in the FM circuitry. Do any other FM stations come in?

If you are interested in having your Marantz repaired, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

Jimmie Monica Hey, Its not a problem with the unit. You have the blue or Blue/White wire hooked up wrong. Disconnect both the blue wire and the blue and white wire and I guarantee the sound starts working on everything. If you have one of those two wires hooked up for a power antenna or remote amp turn on, then switch which one you are using and that will fix the problem permanently. Disconnecting them both will get it to work though. I guarantee it. Please post back and let me know if it works for you. Thanks

I don't know why you need AM, but that's not the issue.
If you have FM and HEAR it ok, then everything is fine. You've hooked it up right.
Not being able to find AM, is in the new radio.
You need to look to see how to tune to AM.
Maybe the paperwork that came with it!

3. If your Nuvi has a FM transmitter, is it selected to "FM" or "Speaker"? The "FM" setting will mute the internal speaker. Setting it to "Speaker" will send sound to the speaker.

if this side of it works then the FM transmitter is faulty

Check that the sound has not been MUTED

plug the earphone into the socket to see if any sound is heard. The socket is also a switch that takes sound from internal speaker to ephone and reverse.
If no sound is hear in either FM or normal mode your unit is faulty and needs repair

there is a safety brake wire that needs to be hooked up. If it was installed professionally, have them explain it to you.There is not supposed to be any video players in view of the driver while in motion. Stop your car and put on the parking brake. If you installed it yourself, you probably didnt hook up the wire. Look inthe install manual for DVD safety wire.

I have a similar problem with a Rockford Fosgate MP3 deck. Mine will get FM just fine (about half the time) when you first start the car, but over the course of a few minutes, the signal will break down until there is nothing. The other half of the time, nothing from startup on. Try this, at least; pull the unit and make sure the antenna is hooked up and secure. If that's not the problem, I haven't been able to find anything else, but a few other report the same thing. It might just be time to buy a new unit.

Me too same problem, no audio with the XM. Do you think it has anything to do with Audio-Video out setting on the unit?

If you remove the unit from the dash the top, take off the top cover, no screws you can acess the CD slot. Remove the 4 screws holding the CD player in place and the ribbon cable and you should be able to remove the CD from the slot.

Hooking up the AM antenna loop should not have fried anything, as I know lots of peeps who have done that. The FM RF amp. sounds like it may be at fault. The only way to tell if its bad is by hooking up an RF generator and I would be surprosed if you had one of those laying around. Disconnect the unit and take it to a repair shop.. If its an older model Time to get a new one. Good Luck
