Listening to podcasts in a car

I usually work downtown and I take the subway for my daily commute but in January, I'll have to take my car to drive to my client.  Last fall, I bought a new car radio with a mini audio jack to plug in an MP3 player and WMA/MP3 playback from a CD or a UBS device.  All of this for a mere $99 and installed for free at BestBuy!

I first plugged in my Zune in the mini jack but I found that it's really not usable while driving since you need to use the player.  Some radios have iPods connectors that let you control the player from the radio, that make more sense.

The best way is to copy a few podcats onto a USB stick and plug it in the USB connector.  I also tried to plug a 80GB external HDD and it worked however, my radio can only read something like 128 folders and it has a limit on the numbers of songs/files it can read.  I guess that more expensive units don't have this limitation.

Anyway, this is a great and cheap way to listen to podcasts while driving in traffic.
