Griffin RoadTrip FM Transmitter for iPhone and iPod (Black)

 (164 customer reviews)

This is a great and useful product, but must be turned to European mode to reach 87.7 - 87.9 since for some reason Griffin thinks that they are not allowed to use these frequencies (they are).

On the FM transmitter box, push the middle button (Function) and then press and hold the "Mode" button (the right one) for approximately 10 seconds. When you let go you will see a menu for "Us" "Eu" "Ja", select the middle button, "Eu". Let the device sit for a few seconds until it goes back to the main screen, then tune your radio and the transmitter to 87.7 - 87.9! Now you can use the device on the frequencies that will rarely give you interference (I have the best luck in St. Louis with 87.7).

I have owned many Griffin FM transmitters for the iPod and iPhone over the years, and a couple from their competitors. I keep coming back to Griffin for their high quality products, which when properly used provide the best sound possible over an FM transmitter (even better than most wired FM transmitters).

Several reviewers have mentioned running the Roadtrip in its "EU mode," which is excellent advice. 87.7 FM is the going to provide the clearest frequency in most locales and almost all vehicles. Other FM frequencies' reliability will vary greatly based on the stations in your area and the sensitivity of your FM antenna. My wife's Griffin iTrip Auto FM Transmitter with SmartScan, for example, transmits flawlessly on 104.1 FM via her Subaru's head unit here in Seattle. In my Audi, only 89.1 and 89.3 seem to work with the...Read more

Over all this is a nice looking device The transmitter works well in my Honda Ridgeline, it comes in as clear as any other FM radio station.

Griffen could be a bit more careful with the form and fit. One of the buttons was too tight and I had to cut it back a bit with an exacto knife to get it to stop sticking.

The one thing this unit lacks and it is not made clear in any reviews I read was that while it is true that it pauses the music when a call comes in and plays the ring tone over your car speakers it DOES NOT play the callers voice over the speakers. What an oversite on Griffin's part! The unit is really complete, except for being able to take a call through it.

Griffin if you are listening, I have no problem paying $60+ for this unit if I could hear the caller over the speakers and use either the iphones built in mic or a mic in the RoadTrip but as it sits now I am tempted to give it back. Just an FM transmitter is not worth this much money.
