Question about Sony CDX-GT21W Car CD/ MP3 Player

Open Question

My CDX-GT21W is wigging out. I replaced my battery, and when the radio powered back on, it displayed every digit/symbol on the display. In this state, no button worked except 2. The DISP button scrolls through the all-on state described above, some repeating asian characters, some repeating shapes, and blank. The source button puts a more typical display and turns on the radio at max volume. The tuner doesn't work (seek+ goes to 96.1 and repeat presses do nothing), and pressing the volume knob scrolls through some of the proper settings, but those settings aren't adjustable: turning the volume knob in one of these setting modes just turns the volume to max again. Switching sources automatically turns the volume to max. The off button turns the unit off, then 2 seconds later, it tries to eject a disk and turns back on to the all-on display state again. I have tried disconnecting/reconnecting the battery several times again to no avail. At a total loss...

If you stop by any car stereo shop, you should be able to purchase a wiring harness that will plug into your car's plug. You can then wire it up to the wires coming from your sony by matching up the standard wire colors.

I have a # symbol in place of volume strength


Here is a link to the user guide: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T6400_User_Manual_E.pdf

You might try reprogramming back to a very basic function by turning off any special features such as VOX, VibraCall, Interference Eliminator Code, Qt filtering, etc. Then see if the radio works any better. Also replace your battery pack with a known good battery, or trade batteries with a working radio.

Best regards.

Hello,

What this code indicate mean that your radio have have been compress with power however the can also be an indication of lower power supply but most of the time is always power compress.

What you need to do to solve this code problem is to put off the radio for some time allow it relax, then remove the battery if possible after some time replace it if you are able to remove the battery then put on the radio and operate it.

Good luck.

I have power going to the unit yet there is no display,a sony cdx-gt220,i know i have power because it is loading and ejecting cds yet no display.please help,its doing my nut in!!!!


I have a Sony CDX GT 530U. I had a problem with no display and I thought no power period. I did not try to install a CD, so maybe I did have power to the CD motor but no display. This was frustrating because I could get the old factory Nissan radio to power up and work so I thought I had a dead Sony unit. After a lot of monkeying around, I discovered I had blown a fuse while installing the unit (you should disconnect the negative terminal of the battery when installing the radio... which I thought I skip, that was a no no.). I had checked the auto fuses, those cheap little plastic fuses behind a panel below the stearing column inside most cars, at least all the fuses I thought went to the car stereo. Turns out I missed one that was labeled "Batt" or something like that, which was the constant power wire to the car stereo. There was another fuse for the Accessory power to the car stereo (the main juice went the key is tuned to ACC or Start position). Turns out the Sony unit display runs off the constant power, or at least the unit on/off button runs off the constant power wire, so even though the ACC power wire was live, the Constant power wire had a blown fuse and the unit would not turn on. Check all your fuses inside the car, I bet that's your problem. Constant power on my Nissan Sentra was a 7.5A fuse, while the ACC power ran off a 15A fuse, but your vehicle may vary. Good luck.

CDX changer has power but doesn't want to eject after flat battery


i resolved this myself in the end.
I unplugged the audio & power cables whilst the stereo and engine was running.
Then plugged back in.
I turned the engine off and stereo off as well.
I then unplugged audio and power again from the back of the CDX, left it unplugged for 10 minutes whilst the engine was still off.
I then plugged the leads back in and turned the engine on. the stereo recognised the CDX, but stayed on displaying "CD Checking". I switched to radio for 20 seconds, turned back to CDX and it selected CD 1 and has been good ever since.

I'm rather pleased with myself!
