I just installed this into my 99 F250 and the functionality of it is great. I can load up my 16 gig flash drive and listen to as much music as I want to in the short drive to work. What's a radio station? Most people are complaining about the remote not working but you have to slide the battery under the the little metal tab instead of slapping it on top. I also have the bluetooth and GPS modules for this and they are great. I would recommend this to anyone that wants a decent stereo/more bang for your buck.
