I work as a cable installer and am looking for a unit that will play .mp3’s (preferably some sort of flash media) and AM/FM radio to enjoy while I am out in the field. It needs to have a 3.5 mm jack, an easy to see and use display, somewhat small in size and durable and able to take a bump and be used out in the elements as I work in some pretty hectic conditions at times. Any recommendations for me?
