Is it possible to have two Car Stereo?

[rion]

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

Opo, you can set a particular FM frequency to tune in...

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

yes, all controls will be through the modulator or the remote. just make sure you buy those with remote version and resumable song track feature. (last time checked, cdrking costs 880 pesos)

yung mas mura kasi after shutting the car off. pag restart uli. balik song track 1.

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

yep, the Ipod will just function like a common flashdisk. so no need to charge the Ipod.
it also has a built-in audio input. so you can also use a phone with mp3. or a no-usb-plug mp3 player. or if you prefer the Ipod controls, using it's headphone out to modulator's audio-in.

just remember never set modulator volume loud. to avoid overdrive or distortion. use the HU's volume control instead. it is also advised not to set the mp3 files in deep sub-folders. matagalan mag-scan yung modulator.
