kyheng said:Pdguy, not to flame you. I have used a USB pendrive like what you said on my wife's car, the quality is so so only. Then i tried on my car with amp, also the quality is not what I'm expecting... The gadget is 100 and pendrive is 200, then a basic HU is 300, so total is 600. With this 600 you can get a Pioneer or Kenwood with mp3 function already. Only your way is more flexible if you normally transfer alot of files from 1 pc to another. No hard feeling please.
