YES i KNOW MOST OF YOU GUYS ALL READY HAVE ONE BUT IF YOU KNOW SOME ONE WHO NEEDS ONE PLEASEA MAKE THEM AWARE OF MINE THANK YOU The unit is 2 months old I bought it new and I was just married and I would much rather have an LCD tv for my new apartment so I still have the warranty papers and I bought it at a local store here (NC)who is a Pioneer dealer AUDIO EXCELLENCE aka CS MOTORSPORTS 2008 TACOMA Scosche dash kit if you need it $750.00

So do I need a TV tuner as well as the converter? I know it is called a CONVERTER but is it whatever antenna I choose, converter, TV Tuner to AV in and then watch TV? ALSO do I need to have the bypass to watch TV while "in motion"
