First, whoever said that there are 8 presets must be thinking of some other device. You only have 3 presets here, but you define them yourself from the whole FM range, an you can always deviate from them. Hence, this thing has an advantage over, say, the iTrip because you can easily surf between three stations if the one you’re listening to now starts getting static.

Second, I find it powerful enough in most situations. I live in Boston, and drive around it often enough. Downtown, most stations will give you a small amount of interference, and that is probably the best you will get. Drive around the suburbs, though, and you can easily find around 3 stations that will play almost as well as your CD player in terms of quality.

The secret to this is to set your iPod volume somewhere around the middle to upper two-thirds of its capacity. If you set it to the maximum, all bass lines will be completely distorted. Set it to the middle, though, and you’ll have rather crisp audio, although you will have to compensate for the lost volume by turning up the car radio. Hardly anything to complain about, though.

My two complaints with this device are these:

First, the marked price is far too high. You can find a much cheaper device on eBay, or even in the Amazon marketplace. I paid around $20 for it, plus delivery.

Second, some types of music sound distorted even at medium volumes on a lot of the stations. I have in mind the Waltz of the Snowflakes from the Nutcracker when I write this. Beside it, just about every song I played sounded clean, although sometimes a given station would encounter pockets of interference.

Given that a more powerful transmitter would probably end up messing up the radio reception of neighboring cars, I’m prone to think that this is an inherent problem to all FM transmitters. I think this is one of the better ones, though, because of its preset options, its ability to scan the whole FM range, the fact that it doesn’t drain your iPod’s battery, and the fact that you can manipulate your iPod volume on it for better performance. The iTrip can’t do three of these. You will, of course, have to sit down in your car and look for usable stations manually, .2 by .2, but ultimately, and if you have no other option available, I think you will find this device to do a good job. Just do yourself a favor, and find a cheaper source.

I have been a great fan of Griffin’s products. I believe that they are generally engineered well and the consumer gets a good quality product for a reasonable price. With that said, I was a bit disappointed with the iTrip Auto. I have been using a low-end FM transmitter (Belkin Tunecast II) for most of a year now, and use it as a baseline for comparison against Griffin’s offering.

The Belkin product also plugs into a cigarette lighter for power, but does not charge the iPod. The Belkin gets signal via the headphone jack on the iPod. By contrast, the iTrip connects via an iPod dock connector and provides both power and signal connections simultaneously. The Belkin’s power cable is an accessory and can derive power from two internal AAA batteries. The iTrip must be plugged into the car to work. The only benefit to the Belkin on this point is that my car’s cigarette lighter is not powered when the engine is off or the key is on ‘radio only’. The ignition must be at ‘on’. The Belkin still provides FM transmitter function with the engine off. The AAA batteries also remember which station freq. is being used, when the unit is off. One of my first concerns about the iTrip was to reset the freq. every time I use it. Not so. It seems to have non-volitile memory for this. Once it was initially programmed, it seems to remember the station.

The iTrip’s controls are simple. Plug one end into your car; the other into the iPod. There is a +/- button and a Select button, and a lit LCD display showing frequency. Simple tune to a station that is not being used in your area, and hit ‘play’ on the iPod. It’s that simple. Griffin’s build quality is of the usual high standards. The front of the iTrip control is a glossy plastic that matches my black iPod. The back is rubberized. As far as fit-and-finish, my only complaint is that the keys rattle when the unit is shaken. It makes the unit feel cheap, but didn’t effect functionality.

In use, I find the iTrip’s sound to be a bit crisp and lacking in base as compared to the Belkin. And the iTrip seems to pick up static ‘pop’s’ and ignition noise when I use certain accessories (e.g. – windshield wipers). I could blame this on poor shielding in my car’s wiring, but the Belkin doesn’t pick any of this noise up. Just the music. A plus that I noticed with the iTrip is that the iPod’s volume control is disabled. It seems to transmit signal to my car radio at one pre-set level and I use the car deck’s volume knob when adjusting level. By contrast, the belkin unit (being plugged into the ipod’s headphone jack) IS susceptible to the iPod’s volume settings and the iPod must be set nearly to max in order for the Belkin to ‘know’ that there is signal. The Belkin has auto-on when signal is detected and auto-off after 60 sec of inactivity (after which I hear blasting loud static from a car radio with no station playing). The iTrip broadcasts quiet dead-air as long as it’s plugged in. Nice!

My overall impression? Really too bad about the sound quality. I like it over the Belkin in almost every other respect. I will continue to test it in other vehicles; but listening to your audio is the REASON for having an FM transmitter, so the lack of sound quality weighs heavily in my score.

Other adapters that are very popular for the ipod are ipod car transmitters. These FM transmitters allow you to use the radio in your car to play the music that is on your ipod! This can really be useful when you spend a lot of time in your car driving for hours a day. It works by broadcasting your music as a FM signal that your car can pick up. The trick is to find a frequency that is not being used by any local radio stations that allow for you to broadcast on that channel. Once this is found, you should be able to wirelessly play music in your car. This can be a great solution if you do not own a car that has native ipod integration.

Well, if you are lucky enough to have a new car that provides an iPod port, it is a easy as plugging it into the car and you are all set. For those of us that are not so fortunate, our options are somewhat limited. There is one option that allows you to plug the iPod into the cassette deck of your car by using a special adapter, but take it from me, it is a pain. The other problem is that many people no longer have cassette decks in their cars, so this would not be an option if you only have a CD player installed.

Your other option could be that you install a new stereo system into your car that does have an iPod integration. While this is a good option, it is a costly one. Personally, I don’t like the look of an aftermarket stereo system in my car. It often does not match the other controls inside the cockpit and is not as good looking as the original equipment.

What other options do you have? IPod FM transmitters! I personally have a job that requires that I drive a lot. I have used iPod fm transmitters, since I bought my first iPod, and have enjoyed all of the benefits that it brings to being in my car for extended periods of time. I listen to music and podcasts regularly, and my fm transmitter has done a great job in making that easy for me. I have tried many different transmitters over the years, and have dedicated this site to help people find great deals and decide which iPod car transmitters will be the best fit for them!
