Lost all sound from my car radio

radio license lost?
in the users guide read chapter radio
see page words how get my radio lic, code
what does it do>?
or scan the PCM it tells you why.
check fuses. radio./audio/sound /nav

radio dead, that means no sound or nosound nor dial data?
does the am/fm and cd all fail, using real CDDA disks(store bought)
? if the radio is totally 100% dead that is lost power to radio.
fuses or lost ground to the radio.

the check engine light means one thing,.
get the car scanned, 1996 to now, all cars USA.
you scan it, they scan it.
i take it car starts and drives perfectly?
head lights work> and all outer things?

Sounds like vehicle theft issue. Unhook batt for min and see if it clears...like a reboot. If nada then git it scand at partstr

fuses are always first. test the fuses. (is dial dead too?)
and if this new car had a dead battery (discharged)
the radio sets the password bs.
needs an unlock code, that the dealer put in the glove box
and you lost that already? ask them. they have it.
only factory 0EM radios do this,

if the dial is not dead, scans and sound is dead.
some radios brick this way, no sound. but all else seems to work
but on some of , cars, has a seperate radio amp that has its own fuse. we cant guess which of 6 or more audio systems your car
was sold with new. lots.

bricked means , anti-theft feature bs , active.

First impression is you radio is toast. It maybe some component gone bad on a circuit panel inside the radio. Before you consign it to the deep try "rebooting" it. Most electronically controlled radios have some king of logic and memory boards in them ...so treat your radio like your computer when it starts misbehaving. To reboot the radio disconnect the battery (remove the black/negative lead first then the positive/red lead from the battery), put the key in the ignition and try to start the car (it won't of course but this is to discharge any holding capacitors) and turn on the radio ...again to discharge any holding capacitors. Turn everything off and let it sit overnight if you can. Reconnect the battery. The radio should have lost all saved information (time, stations, EQ settings etc) and may now be responsive to button inputs. If this doesn't work then I'd say the radio is a goner.

The only thing that you can do is remove the unit and send it out to a factory approved repair shop, that is it no other choices.

the radio will need a code before it will work again. the rest may be fixed with a reset using a code reader.;

If you have lost the code then you can get it online. You will need the serial number which is on a sticker on the radio you will have to remove the radio to read it. Then google I lost my radio code cant remerber the website but I had no problem getting it. It costs but only a few $

I am having same problem with 2008 g5 , no radio , no alert sounds does anyone know what is the problem

If the battery went dead and you charged it, you need to reboot the system. It has lost them function of radio.
Disconnect both side of the battery and with the battery disconnected, crank the car 3-4 times (This just discharges the computers). Then reconnect the battery cables (pos + first) and you should have a working radio again.
