I purchased a Road Trip with the "New iPod nano Adapter Included!",
only to find that the CHARGER function DOES NOT work with any
"New ipod nano" (4G).
I purchased this product with the clear intent to FM transmit, charge and cradle my "New iPod Nano".
I am very disappointed.
Of course, I expected to get what I paid for, and I requested remedy from Griffin.
I stated that this device will not do as the package claims, and I requested a full refund.
Adding, this device CAN NOT perform its stated purpose(s), I further
contended that the packaging is deceptive regarding the capabilities of
this device.
Mine certainly wont do all three as claimed. Griffin blithely verified this.
My response from "Shannon" at Griffin was that this device in fact "ONLY WORKS WITH 3G", and not (as the packaging indicted) with the ("NEW") Nano 4g, ignoring the legal ramifications.
Thats all they had to offer.
LAME. The lousy customer care disappointed me as much as the product.
I went with the InCharge because of the reviews, and flame Griffin for the above nauseating experiences.

I was very pleased with the quality of construction. Seems pretty sturdy and durable. Works perfectly as intended. There is only one negative, and that is the sound is not the full range. It lacks the depth and clarity of a CD by alot. My best workaround is to adjust the EQ on the ipod to the "classical" setting (although I listen to all kinds of music, mostly metal). Still, not perfect sound, but, hell, it was only $9.95, and at least I can get all my iPod tunes on my car stereo now! Overall, I'm satisfied.

We love it. Sounds great and much cheaper than at Best Buy. I shopped around and this is by FAR the best deal!!!

I found the 4030-ROAD RoadTrip to be great in almost every way. It is certainly much better than the iTrip.

My two feature complaints:
1. The RoadTrip should also transmit the title of the song for my car stereo to pick up and display. I have to dig the unit out of the arm rest compartment where I have it plugged into the recepticle to see the song displayed on the iPod screen. This can be dangerous.
2. When I shut down the car (and the power to the unit) it does not resume the same settings as when I stopped the car. I have to push the connect button again for it to detect the FM station I was using when I shut it down. Annoying.

This device is a nightmare.

The bad dreams began the moment I opened the package and attempted to fit my 80GB iPod w/ video into one of the provided mating flanges. Turns out the only one that fit was for a different iPod and then only after some filing of plastic. And, of course, I had to remove the iPod from it protective neoprene wetsuit, which would have been very nice to have when the iPod fell out of the Griffin 4031-RDGC RoadTrip FM Transmitter and Car Charger for iPod (Charcoal) ... standing still in the driveway.

Things went downhill from there as I tried to get music through the car's tuner and into my ears.

Okay, true, I live in an FM-RF saturated environment. So I wasn't expecting optimum performance close to home. But none of the three frequencies auto-scanned by the Road Trip were at all usable. Manually tuning a dead band on my radio - and incrementing Road Trip to match - produced an interference-ridden, wheezy little simulacrum of the strong studio mixes in my Playlists. Damn disappointing for a hundred bucks.

Worse, on recent rural road trip my Road Trip was even more galling. With no audible stations within two guard bands either side of Road Trip's self-selected optimum frequency, there was still plenty of harsh hash, multipath "swang", and annoying collapse to mono.

So it's gotta be my vehicle, right? It's a 2000 BMW with a decidedly Bavarian audio system. Maybe it's just a Germanic engineering attitude problem? Nope. Road Trip fared no better in my wife's 2007 high-end Toyota, a vehicle with impeccable modern electronics.

In desperation, I tried Road Trip's OTHER route: a direct output jack (1/8" stereo), bizarrely (and inconveniently) located on the power plug. At least I'll get clean audio straight into the preamp section of my car's system?

No such luck. The Road Trip's output impedance is severely mismatched to everyone else's idea of the line-in spec. It is neither line level nor headphone level. And the result is, like, 20% harmonic distortion. And, of course, no way to attenuate the output; it just smashes its way in and clips like a [...].

Unusable for audio, I now have a very expensive iPod charger that sometimes - when it wants to and obeying no logic that I'm able to figure out - supplies a trickle of current through to my iPod, but then shuts off well shy of full charge.

These issues seem baked-in and endemic, not at all the result of poor manufacturing or lax quality control. These are basic design flaws.

Succinctly: This device is an unmitigated piece of crap. Do not buy it.
