Sony CDX-3100 - Unit keeps resetting

Hi, I wonder if you can help - I've just taken my Sony CDX-3100 head unit out of my old car and fitted it into a new one. The unit worked fine in my other car, no problems, but since I refitted it, it no longer stores any of my EQ settings or stored radio stations. I set everything up, but next time I switch the ignition back on, the CD gets ejected and all the settings and memories are reset to default.
I followed the instructions in the manual - when I installed it, I pressed the small reset button but this doesn't seem to have done any good. I have unplugged the unit, re-plugged it, then pressed reset but with no joy.

Any help gratefully received

Cheers
Dan Trussler

SOURCE: 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!

OK. Here's the deal. There are two "power" input lines. A RED and a YELLOW. RED should be connected to your vehicles' ignition or key switch. YELLOW should be connected to a "constant" power supply directly from the battery.
If you have a test light, you should be able to find both at the fuse box. Just clip the alligator clip to the frame somewhere or to the edge of the cigarette lighter and probe the fuse box turning the switch off and on respectively. (test lights are very inexpensive, about 4 or 5 bucks at the auto parts store).
Hope this helps.

Don't know if you have an external antenna or one mounted in windshield but you should be able to find the coaxial heading towards the back of the radio. Make sure that it is plugged into the radio.

CDX-S2200 fitting to old golf


haha, yea sorry about that must have clicked the wrong button... if they spliced that old sony harness to the factory harness and did not cut the factory plug off then you can go to you local bestbuy or car audio store and get an adapter for your factory harness... but, if you have the tools and the time, its faster and cheaper just to hardwire on the new one... as for an adapter to convert the old sony to the new sony plug... ive never seen an adapter for that...

MEX-BT5700U, no sound in speakers in CD source, tuner source OK.


What many people do on this model is connect the remotes wires improperly. Use the solid blue wire for the amp and the blue with white stripe for the connection to the car.

How to hook up a head unit to an amplifier,when the head unit has no RCA plug ins? It was done before in my old car now i cant remember how.


Here is a link to owners manual for Sony CDX-GT300.
http://www.docs.sony.com/release/CDXGT300.pdf
Here is a link to installation instructions. It looks to me that there are front and rear line out RCA connectors on the back side of your head unit. (Unless, this is not the model of your head unit)
http://www.docs.sony.com/release/CDXGT300_Installation_Guide.pdf
There are devices that are capable of converting speaker level output to line level (RCA) output. I know Scoch is one brand, and here is a link to others.

I need to know how to reset my cd player


I have the Sony CDX-GT200 unit personally. On my unit, after you remove the faceplate, there is a reset button towards the left of center on the head unit itself. However, I don't see it pictured in your models Owners Manual. Here is a link to your manual.
http://www.docs.sony.com/release/CDXGT210.pdf
Here is a link to my manual for illustration purposes only. Look on page 4.
