I am looking to upgrade my car stereo to an mp3 player, I am only planing on keeping my car another two to three years max so I don't want to spend too much money, but I would like to have mp3 or if possible even wma. I was at best buy today and saw two that were in my price range, the Pioneer DEH P4500mp and the JVC RDS890. These two units do not do wma but they are under 200 which is HIGHLY preferred. I can't have this affecting my DVD buying habit. Do I really need wma? Or is mp3 enough. Are either of these two units worth getting? Would I be better off ordering from crutchfield, (I saw a panasonic on crutchfield for cheaper then both units and it played wma) and installing it myself? Mind you I have no technical skills whatsoever! I could probably persuade a friend to do it. Any incite will be much appreciated.
