Car Stereo Adapter

[rouxster]

That is your expert!! I stand corrected. Good post kabeyum. Is it the FCC that regulates how strang of a transmission each device has and that is how they regulate which signal takes precedence?

You can use any gadget that an iPod can use (direct line-in, cassette adapter, FM transmitter, etc.). Just pick up an adapter for Treo's 2.5mm headphone jack. For cassette adapters I've read that Sony's is very good. For FM transmitters, Kensington's is probably the best sounding, but there are a zillion other solutions (you can read reviews over at the iLounge. Of course, the best quality is to plug the Treo in directly to your car's head unit's AUX line in. If you've got one, you'll need either 3.5mm male to 3.5mm male or 3.5mm male to RCAs.

P.S. If you're going to go with direct-in, you may want to see if Radio Shack has a 2.5mm male to 3.5mm male cable or a 2.5mm male to RCA cable. You wouldn't then need the adapter dongle.

Also If you have an xm Roady that had the plug for sending stereo signals throughthe car plug it will work, you just need to turn on the xm too!
