Hello All. I'm hoping some of you guys/gals may have done the same thing and have figured this out? And help is really appreciated.

I just bought the Virgin Mobile Silder Sonic...because it has the MP3 player ( I know it's not the greatest...but I kinda like the phone!). I'm trying to use the Slider Sonic as an mp3 player, and have the mp3 play through my car stereo as I drive to work. I researched this a bit and this is what I bought to do this.

1.) Slider Sonic phone
2.) Radio Shack 3/32"-to-1/8" Wireless Phone Headset Jack Adapter (Product # 274-004)
3.) Wireless FM Transmitter with stereo input jack (no brand name, from Ebay)

Here's the Problem:

Everything its set-up correctly. But when the Mp3 plays...for some reason the music only comes out of the right side speakers of my car stereo!

What's going on here? I've tried to do some online research on the different types of jacks, whether they are 2, 3, or 4 pole jacks, stereo, etc.

Some people say the Radio Shack adapter's don't work well. But...this one states on the package that is IS a 4-pole jack connector. What is the headphone hole in the Slider Sonic? I assume it's a 4-pole as well?

I'm trying to find the bad link in this set-up and fix it!

Also...what is the best FM Transmitter to buy for use with the Slider Sonic? Anyone use an FM Transmitter in their cars with success with this phone?

Thanks for reading and for your help!
