Is it possible to have two Car Stereo?

[OTEP]

with regards to modulator... it doesn't require charged mp3 player. it only needs a flashdisk/Ipod with mp3 files inside... it's wireless. just tune in to a preset fm frequency.

I'd just like to clarify po.

So I can just stick in my USB flashdisk full of songs into that modulator and it will play through an FM station.

So it means, I will be using the modulator to select tracks, etc.?

What if I use an iPod? I will also control it through the modulator?
