Radio Dead Until Key Is Turned Off,,,and On?

[steven c]

My new to me 04 LX470 has a radio problem which I am hoping is not leading to replacing it. If the radio or CD has not been turned on when the car was started and you turn it on there is no sound. Everything on the screen looks normal and on the nav screen it shows the volume going up...but nothing. Until you turn the car off and then restart it with the radio turned on and then it works. Any help appreciated.

Some clarification. The car is running. the radio/CD is on and it works fine. You shut the car off. It does not work. Do You put the ignition/key in the accessory position? Or, the car has been running. You never turned on the radio/CD while it was running. You turn off the car. If you then go to turn on the radio/CD it won't play. Did you turn the ignition/key to the accessory position? You say the volume level registers and the nav. screen also lights up. Can you use the nav. screen?

Does you year and model have a mute button on the steering wheel or head unit?

No mute button. You start the car with the radio off and it will not produce volume until you re-start the car. Have not tried the nav but all other display functions work. Thanks!

I'm certainly no expert with this, but since the head unit is apparently receiving power,(volume shows up and down), I wonder if it is the amplifier. But that would not explain why it is intermittent with the ignition on/off cycle.

Let's see if somebody else chimes in here.

I'm not too familiar with the LX, but do you know if yours ever had a factory installed cell phone? If so, perhaps there is a loose connection somewhere that is causing its Mute feature to activate.

[steven c]

No, it has bluetooth and a loose wire just doesn't make sense with the sequence needed to get it to work. I think the amp idea is a good one. Anyone know where it is?

No Steven, I don't know where the amp is. In some models it's under the passenger seat, others the trunk, etc. Just call the dealer and ask. It wont cost a dime.

Hi, I have the same year and model & having major issues with the radio/ multi function display. Did you ever get this resolved?

Strange, 4yrs ago on my 03 lx, I pulled the tool bag out the side compartment with the lug wrench & stuff in it one day & my radio went mute. I turned off the key switch, put the bag back in it's location & the radio jumped back on & had no problem since. Weird.
