iRiver AFT 100 Mobile FM Transmitter Review

This little gadget definitely exceeded my expectations for a radio transmitter.  We just used it on a trip from upstate NY, through NYC, onto Long Island (you might have heard that there are a lot of radio stations in NYC) and only needed to use 2 frequencies for the whole trip.  Using our first setting it wasn't until we hit a station using that frequency that had a full blown signal that we finally started to get a little static through the music coming from the MP3 player.  When I turned it off the radio station was coming in loud and clear.  Weak stations are simply overwhelmed and overridden by the IRiver transmitter.  Found a second frequency without a strong signal near NYC and was able to use that until we headed back upstate.  I had another transmitter years ago with a limited frequency range and it barely worked even through the radio wasteland of upstate Vermont, the IRiver simply overpowers static and weak stations and plays your music loud and clear (well, as clear as a good radio station would be).

Just find a frequency with little or no radio broadcast signal, tune the easy-to-read IRiver to that frequency, sync up the volumes and forget about it.  We got the best results by cranking up the Zune to about 25 or 27 volume (almost all the way, just before distortion would creep in through headphones, etc) and then play with the radio volume using your car's radio volume control.  Piece of cake.  I don't know how you could do better if you're going to use a radio transmitter.
