Ipod
I tried the Belkin wireless fm transmitter, and had nothing but problems. Not sure if it was a bad unit or not, but I bought one of the cassette adapters and that thing works GREAT! No static, no interference of any kind.....Works like a champ!
I use the Belkin TuneCast II w/ the AC adapter. Do not buy the battery only IPOD white edition one, it doesn't have enough juice to work appropriately. Same goes for the Tunecast I, the previous ones were a joke as far as quality and performance. As a note, no matter which fm transmitter you get, you have to crank the volume on the mp3 player to max for the transmitter to realize it is on and wants to be broadcasted.
Key tip is to find the radio station in your area that is the least competition for you to broadcast over. In my area, the clearest signal is achieved at 101.9.
Go here: http://fmchannel.sirius.com/ and type in you zip code in the box at the upper right and it will tell you the best options as far as stations to use for the transmitter.
I have the Zune branded transmitter (Belkin made, I think), and it is barely adequate. It sounds pretty good now and then, but a lot of clarity is lost on the vast majority of songs, and too many of those also suffer from a harsh distortion in the lower frequencies.
From the reviews & advice I read, these issues are pretty typical of all the FM transmitters.
I did some online research and it seems the FM transmitters will work sometimes, but many have reported less than satisfactory performance. There are also inline FM modulators that plug into the antenna line and these reportedly work better but are more expensive. Another alternative is to use a radio that has a plug, many aftermarket units have such a plug, Dr.Dons will modify a stock unit with a plug for $100 and I have seen stock GM radios on Ebay that have been modified.
For me, I will use the cassette adapter.
