Griffin iTrip Auto FM Transmitter for iPod (Black)

The Griffin iTrip Auto FM Transmitter with SmartScan wirelessly sends music from your iPod to your car radio so you can listen on your car stereo speakers. It combines Griffin's renowned FM transmitter technology with an integrated charger. Designed specifically for use in the car, the SmartScan function makes it easier than ever to find the perfect frequency. SmartScan scans the radio dial for the three best frequencies and saves them to the preset buttons. The high-contrast display is easy to read in any light, and the three-stage light ring changes color to indicate charging status. Compatible with iPod (4G, 5G), iPod nano (1G, 2G, 3G), iPod classic, and iPod touch.

Owner Reviews, Ratings, Comments and Criticism
On my quest to find a FM Transmitter, I bought a different itrip from Griffin, but it did not charge my ipod nano 4th Gen. So I called Grifin and they told me that in order to charge my ipod nano 4th Gen that it needs to be an itrip with Smart Scan technology. So i returned it and bought this one, and i'm very happy with it. 1. This unit charges our ipod nano 4th Gen no problem. The ring of light on the cigarette lighter plug lights up red when initially connected denoting power to FM transmitter, then amber once the ipod is connected (charging), and then it turns green when the ipod is fully charged. 2. I have a sealed radio in my car so therefore don't have an audio input unfortunatley (2005 Volvo s40 2.4i) and so FM Transmitters are a way of life for me. Your not going to get the perfect sound quality from these like you would with a direct input, so check to see if you got an aux input in your car first and then just buy a charger and a double male head phone wire. I have a Sirius Radio has an FM Transmitter so i'm use to dealing with changing frequencys every so often. I live in NJ and am in NYC and Long Island a lot. My car can tune to 87.9 which I use for the sirius radio almost everywhere, but sometimes while in NY I use 93.3 (pretty high on the frequency list, but for some reason it's clear). 3. Check to make sure your car can go into 87.9 range first, these channels are hardly ever used by radio stations, then switch this grifin itrip autoscan to international frequencies just press function, then press AND HOLD mode for roughly ten secons until a new menu appears. It'll give you US, EU, and JP choices above each of the three buttons on the itrip. I picked JP (for japan) which enables all the normal US frequencies plus the lower range, lower then my car can go, my car only goes to 87.3 or something. A funny thing is that when i tune my car and itrip to 87.9 i get static, but if i keep the itrip at 87.9 and tune my car to 87.8 it comes in perfectly clear. It doesn't do that in my wife's car, 87.9 is 87.9. Just set one of your car radio presets to that and your good to go! 4. I took someone else recomendation to adjust the ipods equalizer to "Acoustic" and that definetly sounds better. 5. Long story short, I like this product, I got it for a heck of a lot cheaper then any FM transmitter at the apple store. One downfall which people do mention is that it is a tad bit hard to read the display of the itrip when you got a glare, but you can set your own presets on the itrip. Autoscan function is stupid, but apparently this is the model that'll charge the ipod nano 4th gen. Scan the radio yourself for static/ or free channels and then tune the itrip to those.
