I tried few options to play MP3 podcasts/USB but I find following one of the best option for my ole Prius. I am using following and can be had under $30 for all: - MP3 Aux/Bluetooth player (Ebay for $8 shipped from China) , this player keeps playing MP3s when powered - 16GB microSD card - Usb Charger - MPOW noise cancellation device for AUX (A must when driving at 70MPH on highway), I think its under $10 All stored away in secure console and out of way.
