If the dealer had change the part you sayd ask them to reset the ECU or the main computer off or car it should solve the problem

You may download a copy of the installation/connection manual here. The wiring diagram is on the first page.

The directions to remove the Sony CDX-S2000 are in the operating manual, starting on page 15. You need the release keys that came in the original packaging before installation. The installation manual also shows these steps. First remove the front panel by pressing in on the bottom left corner. Then pull the panel towards yourself. This is shown on page 7. Next engage the release keys on sides of the protection collar. (Use the wide end of the keys oriented as shown in the picture). Pull out the keys to remove the protection collar. Reverse the release key and face the hook on each key towards the AM/FM/CD-player. Insert the keys together until you hear a click. Pull the keys out to unseat the unit. Now you can pull the unit out of the bracket.

Sony has the installation manual and the operating manual on the product site: https://www.sony.com/electronics/support/mobile-cd-players-cdx-series/cdx-s2000 . The current link to the operating manual is https://www.sony.com/electronics/support/res/manuals/W000/W0002058M.pdf . The link to the installation guide is https://www.sony.com/electronics/support/res/manuals/W000/W0002059M.pdf .

I hope this helps. If you need the keys, I found apparent replacement keys for sale at Amazon here: https://www.amazon.com/Sony-Stereo-Radio-Removal-3-246-471-01/dp/B001DFTTDK .

here it is

Just connect together the solid blue wire on the main harness to the radio with the blue/striped wire. The blue wire is for the power antenna and the blue striped is for the remote amp. but if not connected together only the fm/am has outputs to the line output RCA jacks. I learned this through Sony's tech line and it works perfectly now.

sounds like a bad ground connection..
