If you don't want to bring your ipod with you everywhere or have it in the car all of the time, there is another option. Many of the new car stereos feature a USB port in which you can attach a USB flash drive with MP3 files and play music directly off of that. That is a great and cheaper alternative than getting an MP3 player. Why travel with your expensive MP3 player when flash drives are a dime a dozen. This is what I will be looking for in my next car stereo. I came across a video showing the use of a flash drive with a car stereo. Enjoy. =)
