I bought an iTrip at Target recently, and much to my disappointment, I've not had that many chances to use it. I can't really get the hang of it, and I can never get it to go through to the radio (Okay, maybe once, but that was in the country.) It might be because all the frequencies are taken up by radio sations already, because I sure can't find an empty one. If this problem was removed, then surely it would be a top notch product.
Tell us how you really feel. I bought one. Hardly use it because I just rather burn my favorite songs on MP3 CD anyways and listen directly from the car stereo. And if you decide to buy one, you really have to buy the more expensive ones where you can change the frequency on the unit itself, without going into the whole iPod playlist thingie.
i have the iTrip and it works fine for me because i'm not near a dense radio station area. I took it to San Francisco and tried it and it was basically useless. If you are near a city center dont bother with it. Use a direct cable to the stereo.
I bought an iTrip and it works great. Sure, every once in a while it'll get some interference, but that's very rare. I also live in the city of Los Angeles, so there are very few stations that work but it's still perfect.
Your best bet if you're having problems is to go on the Griffin website and download extra stations. I use 87.5 and 87.7 which are usually empty, even when going on road-trips.
I've had problems with the actual life span of the iTrip, though. I ordered one, 3 months later it broke and Griffin sent me a new one. They're just as fast as Apple's replacements, but you have to call a long distance number to get it sorted out. When the new unit arrived, it was broken as well. My sis just got one and when she pulled it off the iPod, all the guts came out too. Griffin is in the process of replacing that as well.
I love my iTrip, personally. I've used it from MA to LA and everywhere in between and found that only near city centers was it unusable. For the most part, I was able to leave it on 87.9 the whole damn time and have radio-quality music of my choice.
My iTrip works great, I use it almost every day since I commute about an hour and a half everyday. The 87.9 default station is rarely taken wherever I go, I guess it depends on where you live in the country and the amount of radio stations. Whenever I pass by our local classical music station, there is interference and I hear the songs from the iPod and classical music mixed into one cluttered song.
I bought mine in a Goodwill Store for $7.00. Seriously, in the original packaging and everything. They had two. Never really have gotten it to work though -- very difficult to find an open frequency in these parts.
I love mine. I use it daily while driving to work, and have taken it on road trips with out a problem. I'm going on a vacation to Europe (Netherlands and Scotland) in September, and plan to take it for the rental car. I've downloaded the extra stations for Europe (even decimals, 90.0, 90.2... etc.)from the Griffin website, so will have those available if needed.
I've found that the stations near the ends of the spectrum seem to have the best chance of being free.
I'm surprised that so many peopole don't like the iTrip. I love mine. My cassette player in my car is broken, and there's no line in, so it's my only choice at the moment for connecting my iPod. I live in a city that has more radio stations than any other, and yet I get along fine with my iTrip. Ocassionally I get a little interference, but it's usually pretty minor. I use 87.9, BTW.
Only reason why I dont like mine is because it really degrades the quality of the music the farther away from the antenna you are. The iPod literally has to be right next to the antenna for you to get better sound quality.
