Question about Sony CDX-M730 CD Player

1 Answer

Sony CDX M730 won't operate manually. Remote operates unit fine.

The unit has been installed for five years. Car radio fuse is okay. Manual operation of the unit stopped functioning the other day. None of the buttons operate manually and the internal display screen does not illuminate. However, the remote for the unit functions fine and all its control buttons operate the unit properly.

I successfully reset the unit and still experience the same problems. I don't believe its the problem, but I'm pulling the unit to check the unit's 10A fuse.

Any suggestions? Thanks.

    What if it CAN'T be operated with the remote?? Could it still be the flex cable?? I have the CDX-M730 and it doesn't work with the remote. When using the face panel, controlls are messed up. Close button lowers volume, + changes mode, display (?) increases volume. no CD eject. P.S., a Pepsi was spilled into the face. I cleanedcircuit boards, switches, etc. real good. Doyou think it might be the flex cable, or should I just "trash" this radio?? Thanks, Timm ....

I need a diagram to wire a sony car radio to a 2006 toyota tundra


I'd suggest starting with a radio harness adapter designed to provide wire-ends for the plug head in your tundra, I've found a few on eBay in this search:

Beyond that, here's the wiring diagram & installation manual for your gt200 radio:

and here's the operating manual:

Can you change the radio stations without the remote?


Yes. This is a link to Sony for your CDX-CA900X operating instructions. Look on pages 13 & 14 for changing radio station w/o remote.

Faceplate will not open


Perhaps something is not installed correctly physically. Sometimes if something is a little twisted the way the unit is installed it will keep it from opening properly. Try moving the unit slightly and see if that helps.
