Five FM iPod Transmitters Reviewed

Posted by CowboyNeal on Sat May 26, 2007 09:53 AM
from the for-the-soundtrack-of-your-life dept.
An anonymous reader writes "If you want to listen to your iPod or other audio player in your car, but you don't have a cassette deck or a swanky I.C.E. system, then the answer is to transmit the music over FM to the car's radio. HEXUS.lifestyle reviews five FM transmitters for the iPod and friends, investigating how well these devices cope with broadcasting music over a 2 meter-or-so radius. Some readers will be aware that it's been less than a year since these became legal in the UK, so the majority of iPodding Brits have only recently discovered that they can tune into their MP3 collection on the road."

    Very nice! (seriously)

    I bought a unit that did NOT turn off after the audio signal stopped and I frequently forgot to turn it off manually...which resulted in the batteries being dead 90% of the time. Whatever unit that you buy, I suggest looking for one that has this critical feature.

    Also, if you live in a populated area, make sure that you get one that has a broadcast frequency is FULLY tunable...not just selectable between a handful of discrete values. I live in DC and you are hard pressed to find an unoccupied slice of frequency.

      Wiring the iPod output directly to the aux inputs on the head unit is by far the best route, but consumers need to do their research before they buy a car and/or an iPod planning on doing this. My wife has a 2005 Corolla with a 6 disc in-dash CD changer, and there is no aux input. I can't replace the head unit because it's all proprietary wiring that is dependent on several other systems. After talking to a few car stereo places, it seems like this is increasingly becoming the norm for auto makers. For us, an FM transmitter was the only feasible option, and not a very good one at that, as we live in DC and it's hard to find a free channel.

        First the car audio shops you took your car too were staffed by idiots. Most car stereo installation companies sell boxes to replace the systems your car stereo provides, or has a relocator to put the stock radio inside the dash out of the way.

        At least they should have sold you a hard wired FM modulator. They disconnect your antenna, install this box in line and give you a headphone jack and switch, turn the unit on and it blasts your stereo's antenna input with 100mw at 88.5Mhz FM stereo goodness that can not be overridden by the strongest FM station because it disconnects the antenna when turned on. These things are incredibly cheap and common. companies like Scoshe and MEtra, the companies that make 95% of all car stereo install accessories, make them and recommend them. Any car stereo shop that has even 1/10th competent installers would have told you about that option right away.

        I strongly suggest finding a competent stereo shop (Note it's the one without the ricer cars in front) and talk to them about getting a good modulator installed. they work fantastic and you dont havet o screw with changing the channel every 5 miles because a station starts coming in stronger.
    • This goes for the NYC area too. I'm in north Jersey, about 30mins outside of the city. If a station isn't outright being used, the signal from a neighboring station leaks into it. 92.3 can be heard on 92.1 and 92.5, for example.

      As a last-ditch attempt, I found a website that shows you how to pry open a Griffin iTrip and pull the antenna (a 2 inch copper wire) outside the casing in hopes of boosting the signal output. By the time I was done with it, the iTrip looked about as good as it worked.

    • There's a flipside to the issue of having no unused frequencies. Often, when in city traffic, these signals bleed into nearby cars, covering up the radio station whose frequency they are using. I haven't heard of this explicitly happening with iPod transmitters, but some of XM's satellite receivers are known to do this. http://www.boston.com/business/personaltech/artic l es/2006/12/21/getting_howard_stern_off_npr/ [boston.com] I DJ at one of the stations experiencing this problem (http://wmbr.org/ [wmbr.org], not an NPR-affiliate)

    Personally, I've never had a good experience with an FM transmitter. I bought a Griffin iTrip for about forty dollars, and it wouldn't work unless it was on the corner of the dashboard next to the antenna. It chewed through my iPod's batteries, and even when the radio could pick its signal up the sound quality was mediocre at best.

    Then my friend gave me another transmitter that worked better than the iTrip, but after a while it broke and the sound only came out of one speaker in my car.

    Nothing is going to beat a direct AUX input or an FM modulator. Using Pioneer as an example, accessories for the Pioneer p-bus range from $20 to $60 to add RCA inputs on units that don't have a factory AUX input. An FM modulator can be had for under $40.

    I occasionally find it amusing to tune my car radio to FM 87.9, which (in the U. S.) is the default setting for most of these FM transmitter gadgets. I commute on Route 128 in Massachusetts so there is plenty of company, and more often than not there is an audible signal on 87.9.

    Mostly it seems to be people listening to Howard Stern on Sirius Satellite Radio, but you also get a sampling of other satellite stations and (most likely) iPods.

    The signal will usually be audible for the better part of a minute. Oddly enough, I've never managed to identify the car doing the transmission. You'd think you could tell from the positions of the cars around you and the strength of the signal, but I can't.

    I discovered this because I have an iPod FM transmitter, set for 87.9 myself (after much experimentation I was never able to find any less-used channel).

    What seems perverse that the signals from other cars' transmitters are not only strong enough to hear when my transmitter is off, they are strong enough to produce annoying an audible interference when my own transmitter, inside the car, is on. You'd think a transmitter two feet from the radio would totally overpower that must be at least forty feet away with two car body's worth of shielding in between, but no.

You'd think a transmitter two feet from the radio would totally overpower that must be at least forty feet away with two car body's worth of shielding in between, but no.

      Here are a couple things I believe are relevant. You car is an electrically noisy place, especially the front of the car. This is why, I believe, most modern cars have antennas at the back of the car, away from the electrically noisy engine. The radio is at the front of the car, and encased in a metal grounded cage, most often refereed to a faraday cage. This keeps the electrically noisy engine, and other signals, out of the car. In any case, the FM transmitter has an antenna on it, the length of which is likely around 1 wave length of the 100 MHZ wave, as do all the cars around you. Each of the waves must leave the car, make it to the antenna, so that radio can decode and play the wave. It may be that there are three or more cars around you may have transmitting antennas nearly as close to your receiving antennas, especially if the transmitting antenna is laid across the dashboard rather facing toward the back.

  • All the transmitting devices I have seen are FM based, and as some a number of people have mentioned trying to find an empty frequency is not always easy. Given that there are more free AM channels, I have always wondered why some of these devices don't support AM.

        Not exactly true. You can get AM Stereo. Its just that FM took off before AM Stereo became widespread. But it's a standard: http://en.wikipedia.org/wiki/C-QUAM [wikipedia.org]

        I don't know about quality, as I never used AM Stereo. But some people claim AM stereo gives better stereo separation than FM. Plus at a distance of 1m I don't think interference will be a huge problem (AM actually sounds quite good when you don't have interference. Its just that AM is more prone to interference than FM).

  • I use my iPod in my car with an FM transmitter occasionally and find that the iPod's interface is totally unsuitable for use while driving.
