well i picked up a belkin tunecast II last night... it was dark and late so i didnt spend much time with it, but i was totally unable to get a decent signal with it..
but today i messed around with it some more.. and i figured the short little wire on it (that connects to my zune headphone jack) probably acts as the antenna.. so i took an extension cable and put that on and took off part of my dash and ran the cable inside the dash and wrapped it around my stereo and now it sounds pretty good.. still some slight static between songs or during really quiet parts but nothing real bad.. and plus now the cables are hidden behind the dash
so ill see how this works for a few days
