The front of the Sony XR-CA600X cd changer lost contact to the rest of the radio. the tape seems to work, but the front is off, not even an led is working. what should i check some of the contacts to the front have an 5V output but some of them have none. i sadly can't find any datasheets of te radio.

Those are for the optional CD/MD changer. The deck won't switch over to those inputs unless a compatible changer is hooked up via the bus control. The only way to make this work would require a changer.

Unfortunately, the input on the rear of the stereo are Bus inputs. You must use a controller to use those inputs.

You may download the installation manual from here. The wiring diagram is on page 2.

If you can, try to check and see if both the red and yellow wires are getting power.

There is a guy online selling this radio with the CD Changer, and he calls it the cdx-51. There is one on ebay for around $45, and you can see it here http://cgi.ebay.com/ebaymotors/Sony-CDX-51-CD-Changer_W0QQitemZ290351379165QQcmdZViewItem. Hopefully, with the code, you can find the changer you need.

when something is plugged into the jack (mp3 player ect) there should work when you cycle through the options of the deck such as cd, radio, There should be an aux option when it is plugged in.

How do you solve the problem my face want light up

chek your fuses.

Hook the remote leads from your amplifiers to the blue/white wire at the back of the Sony head unit.

hi sounds like you have the amps switching on via the aerial remote and not the amp remote. easy way to test this is to switch the AF or traffic function on your radio. if this cures the problem then you have the amp remote and aerial remote connected around the wrong way regards Mark www.carradiospares.co.uk
