We're always happy to welcome another computer-interface-ridden hybrid car stereo / multimedia device to the fold, like Roadmaster's VR3 VRCD400SDU car stereo. Not only does it do aux i (so you can use just about any portable audio player imaginable), but Roadmaster were also thoughtful enough to include an SD slot, USB port, and remote control for playing back MP3 and WMA tracks, with ID3 info showing up on-screen. The single din head won't ding that pocketbook too hard, neither, coming in at a lightweight $140 US, which is even reasonable for other players which might only match its CD player and AM / FM radio.
