Looking for a very specific cable for W810i

[TerrestriALien]

Hello. I am looking for a cable for my phone. What I need specifically is for that cable to charge the phone via USB without file transfer and also have a 2.5mm jack. So in other words, one end of the cable is the SE connector and the other split end needs to be USB and headphone jack (preferably male). This cable will be used to plug the phone into my car stereo for playback of my MP3s, and charge through the same stereo's USB port (or car charger). I tried using the data cable for charging, but with the 5 volt pin being in a diffderent location the phone automatically asks to switch to data transfer mode and does not charge (although the indicator says it is).

Anybody know of existance of such cable? Or will I need to manufacture it?

Ive never seen a Male connector at the end but if you do not have your oem headset wires, here it is;

Also, i have the same phone but havent used it in years;
but isnt there a way you can cancel file tranfers while its plug'd via usb?
Ive also read that usb charges the w810i faster than the wall charger does...
