Most factory car stereos made before 2001 (pre iPod) do not have any external audio-in. The few newer cars I’ve looked at have not had any (easily accessible) external aux-in. It can be assumed factory stereos with CD changer capability have some sort of audio-in, but it is usually tied to the proprietary changer interface and can be difficult to “break out” (not to mention usually having to tear up the dash to get to it).

The Belkin Tunecast II is my current FM transmitter of choice (digital tuning, almost full FM freq range, external power, etc). Sounds good. Requires no modification to the vehicle. There’s a small shelf right below my radio where I put the transmitter and I hide all the extra cords in my unused ashtray.

I dont mean to flame, i mean i have an iPod Shuffle laying around with no battery, I’m hoping to replace the battery and use it as a car stereo memory stick xD

WOW! Steve made a contribution!

Lol. Just thought I’d say, I like that PSP mod, too.
