SanDisk Sansa c240 1 GB MP3 Player (Black)

Works better with ROCKBOX firmware.  Not a bad player used it until it died on me mostly as a car kit. Rockbox would allow me to mix songs and turn unit on/off with car ignition and customize the eff out of the unit.  You can flip the screen (which i did to get my wires juxtaposed properly) and get it to play as if you had a car kit.  Kinda reminds me of the "fake car kit" .prc utility I had on my Treo many years back...
