can I connect my shuffle to my car?

IF your car audio system has an auxiliary input you can use a cable with plugs on both ends available at places like Radi Shack.

Generally, a question like yours actually needs more information

HOW DO I DELETE MUSIC FROM MY IPOD SHUFFLE

From your very fine manual "iPod shuffle Features Guide":

Removing Songs and Other Items from iPod shuffle
You can have iTunes automatically replace items on iPod shuffle when you load items
using Autofill. You can also remove items from iPod shuffle manually.
To automatically replace items on iPod shuffle when autofilling:
1 Connect iPod shuffle to your computer.
2 In iTunes, select iPod shuffle in the Source pane.
3 Select the Contents tab.
4 Make sure “Replace all items when Autofilling” is selected.
To remove a song or other item from iPod shuffle:
1 Connect iPod shuffle to your computer.
2 In iTunes, select iPod shuffle in the Source pane.
3 Select a song or other item on iPod shuffle and press the Delete or Backspace key on your keyboard.
Manually removing a song or other item from iPod shuffle does not delete the song
from your iTunes library.

As already stated by 0Ari0, IF your car has an audio input hole for a mini-stereo plug, like the hole on the iPod shuffle for the ear buds, THEN you can buy from Radio Shack (or other electronics store) a cable that has a mini-stereo plug on both ends. Connect the iPod to your car stereo using such a cable.

If your car stereo does not have one of those inputs, you can buy an adapter that goes into the cassette player. But from my experience, those devices do not work very well.

My car stereo has an aux. jack, and also a usb, i can get the shuffle to run off the aux. jack, but it will not run through the usb port. Is there a way to make the shuffle run off the USB ( that way i can control the IPOD from my deck, and not the device itself)?

READ the manual fir your car stero... it should give you the details on which
Audio players can be used through it.

Generally the shuffle is NOT one of them...

The iPod shuffle is not like the bigger iPods. It's just a little audio playback device. It's not "smart" enough to interact with car audio system. The bigger iPods are more like computers, and they can interact back and forth with the car audio system.

Sort of... SOME USB interfaced auto stereo receivers actually use the link to READ the contents of the attached MP3 player as a flashdrive and display track info, etc. They could do the same with a shuffle (as a data storage device) AS LONG AS it's been loaded with songs as files directly from the computer (without iTune).

But I doubt that it could control the iPod shuffle. For what you are describing, the iPod shuffle is a flash drive that stores the files. The car stereo is then playing the files, not the shuffle.

If someone made an accessory, like a car stereo or alarm clock, that could read the files on a shuffle as stored by iTunes and play them, that might be useful.

EXACTLY!

Unfortunately, they don't 😟

I have a Sony CDXGT820IP and I'm currently using an old ipod mini. The batteries in the mini will no longer charge but the ipod dock cable in the sony provides the power thus breathing new life into an old ipod. All ipod menues are accessable on the radio display and navigated by the radio controles. The ipod remains in the glove box. Since I can access everything thru the radio I was thinking that an ipod shuffle would be a perfect device for this kind of setup since you don't need the ipod's screen or controles and a simple aluminum box bouncing around the glove box couldn't get damaged. Has anyone tried this?
Also Apple could come up with a "car" ipod, say 80G, minus any screen or controles but able to interact with ipod compatable car stereos, a less expensive but bullet proof unit that could safely inhabit a car's glove box.
