Review: Griffin RoadTrip All-in-One Car Solution

Pros: Solid FM transmission and charging in an all-in-one package that’s less expensive than only major competitor.

Cons: Large size, proved difficult to adjust for use in our test vehicles, numerous detachable pieces prove overly inelegant ways to attach/detach iPod and FM transmitter, which is not especially useful when removed.

If any accessory maker has consistently matched Apple’s uniquely attractive product designs, that company would be Griffin Technology. From the iTalk to the SightLight to the PowerMate, the company’s iPod and Macintosh accessories have been both visual knockouts and quality performers, uniformly praised for their elegant simplicity.

After winning considerable praise from iLounge and others for its beautifully integrated iTrip FM transmitter series for iPods, Griffin’s new RoadTrip is an unexpected break with the company’s traditions. While reasonably priced and full of interesting-at-first-blush features, the RoadTrip turns out to be little more than a clumsier but cheaper iteration of DLO’s earlier and well-established TransPod three-in-one iPod car charger, cradle, and FM transmitter. Thus for the first time we can recall, Griffin appears to be competing mostly on price rather than on concept or execution, a hopefully temporary change of strategy that only some users will appreciate. Whether the RoadTrip is right for your personal needs will depend heavily on several factors that we consider below.

(Editor’s Note: iLounge has tested and reviewed DLO’s previous generation TransPod, which is mentioned herein for comparative purposes only, and has not reviewed the current version of the product. We do not render an opinion on any differential quality of the FM transmission of the two products, only other features that appear in one product but not the other.)


Unless Apple integrates FM transmission into future iPods, there’s little doubt in our minds that Griffin’s earlier and iconic iTrip transmitters were designed as beautifully as such accessories could be designed. Using the iPod’s screen for channel selection, each iTrip’s small white casing fit perfectly on top of its respective iPod, and without additional batteries provided more than acceptable FM transmission for most purposes. Equipped with an iTrip, an iPod can broadcast to a home radio, a car radio, or any other FM radio you can find; moreover, thanks to Griffin’s unique iPod and software-based frequency tuning solution, and unlike competing products, the iTrip operates even in foreign countries with different radio frequencies.

Though it will inspire comparisons with the iTrip, the RoadTrip is an almost completely different product: it only works with the iPod in a car. Featuring a large white cradle with an integrated cigarette lighter power charger, an FM transmitter, and two detachable extension arms to (separately or together) connect the cradle to your vehicle, the RoadTrip lets you mount, charge, and listen to your iPod while driving without any additional cables. Assuming your car’s power charge port leaves enough clearance for the RoadTrip – which may not be a safe assumption, depending on your car – it’s relatively easy to pivot both your iPod and the RoadTrip’s LCD tuning screen into a viewable position.

Because every blister-packed package actually includes a total of nine parts, the RoadTrip reminded us of Ron Popeil’s infamous infomercials: “that’s not all – you get much, much more.” The remaining packed-in pieces include a white plastic belt clip that fits on a 3G iPod to act as a portable mounting device for the RoadTrip, and an iPod mini belt clip adapter that turns Apple’s packed-in mini clip into the same sort of RoadTrip-ready mount. You mount your iPod on the clip, and then insert the clipped iPod into the RoadTrip’s cradle. A soft in-clip spacer pad for thinner iPods, a white plastic adaptor cap for certain vehicles’ power plugs, and a two-cable bundle round out the package. That’s a lot of parts for Griffin’s $79.99 asking price.

And, as Ron Popeil might add, “wait, that’s not all!” You need the aforementioned two-cable bundle because the RoadTrip’s FM transmitter is detachable. Two holes at the top of the transmitter provide power and audio inputs, hence Griffin’s packed-in USB-to-power cable and a 3.5mm stereo mini-jack cable.

Though the white plastic and silver stickered transmitter isn’t aesthetically impressive, and actually looks like a cheap pedometer, the screen and three buttons are easy to see and use. A separate alternating red and yellow LED light on the RoadTrip cradle indicates that power is flowing to the connected iPod.

Without question, given all of its detachable parts, the RoadTrip is a somewhat less elegantly implemented all-in-one solution than DLO’s TransPod, but then, it’s cheaper and claims to do more. What other single package can offer everything from detachable FM transmission and car charging to belt clipping and car mounting?

Functionality: the Good

After several days of testing, the RoadTrip is at once an easy product to describe in broad strokes and a difficult product to recommend without noting serious issues that may impact certain users. To start with the broad strokes and nice things we can say about the RoadTrip, there’s no question that it works, and works well to perform stereo FM transmission of the iPod’s audio and recharge the iPod in a car.

Transmitter tuning is simple thanks to tactile, front-mounted up and down buttons, plus a simple on/off button that always worked. (The button also flips between station presets when lightly pressed.) Additionally, the RoadTrip’s screen was easy to read during the day and night, thanks to a simple yellow backlight that illuminated the black numeric display, and the transmitter was easier to re-tune than the iTrip, something that proves useful mostly when travelling great distances by land. Most of our driving is local and suburban, so we typically don’t have as much need to change stations to avoid signal problems, but those with different needs may appreciate the RoadTrip’s separate LCD interface.

Even without the use of an unwieldy external antenna, such as the one employed by Sonnet’s PodFreq, we found that the quality of the RoadTrip’s FM broadcasting was quite good – as strong and clear as we’ve ever heard in our test vehicle. However, as with all FM transmitters we’ve tested, there was a very mild static hiss in the signal at all times, which became noticeable mostly at higher volume levels. For this reason, cassette tape adapters and direct line-in/out solutions still remain our solutions of choice for users who have those options.

Recharging is straightforward. The RoadTrip’s built in two-color LED isn’t the best we’ve seen – some LEDs use three colors to indicate two different types of charging, one signaling that 80% of the iPod’s battery has been charged – but it works. Red indicates that the iPod is charging, and yellow is supposed to indicate that the RoadTrip is on but no charging is taking place. Not surprisingly, we had no problem recharging either of our test iPods with the RoadTrip, but we did notice that the light went yellow sometimes even when the iPod’s battery indicator showed that charging was still taking place.

Functionality: the Bad

Unfortunately, the issues we experienced with the RoadTrip were more memorable than the positives of its performance, and we think that many users may have similar gripes, depending on their specific needs and vehicles. In order of the issues presented below, the RoadTrip is most likely to satisfy a user who: (a) doesn’t need to use his iPod with radios indoors, (b) doesn’t want to circumvent the RoadTrip’s FM output by using direct line output, (c) has a car power port located conveniently away from a gear shifter or other existing object, (d) does not need to use both extension arms to connect the RoadTrip, and (e) likes to belt clip his iPod or iPod mini (and doesn’t use a protective case).

Other users should be forewarned. By comparison with DLO’s TransPod, the RoadTrip’s new and different features don’t work quite the way most people would expect them to work, and unnecessarily complicate what was otherwise an acceptable (if also somewhat large) design.

First, many users will be surprised to learn that the detachable FM transmitter component of the RoadTrip isn’t a replacement for either the iTrip or Belkin’s TuneCast II. It lacks both a battery and a battery compartment, and thus cannot run on either its own power or the iPod’s.

As a result, though you can detach it from the RoadTrip, it can only be connected to a personal computer with a powered USB port. If you want to use FM transmission with your iPod indoors, you’ll need to buy something else. And while you may want to broadcast your computer’s audio to a radio, we’d venture a guess that your computer has its own speakers, limiting the practical usefulness of this detachable “innovation.”

On a related second note, an interesting feature in DLO’s TransPod was a line-level output port that allowed users to circumvent the FM transmitter and instead plug in a cassette tape adapter or direct line-out cable to the iPod. Griffin doesn’t include such an output port. Though you could conceivably accomplish the same result by detaching the RoadTrip’s FM transmitter and buying a separate female to male adapter to interface with the male stereo plug found on the RoadTrip, Griffin could really have done better by flipping the stereo ports on the RoadTrip and the transmitter, and including a different cable. As is, no adapter is found in the box to accomplish this purpose, either.

Our third and fourth issues relate to the RoadTrip’s two extension arms. The main body of the RoadTrip is a sizeable white plastic cradle that attaches to three or four parts: the iPod (with attached belt clip), the separate FM transmitter, and one or two of the arms. If you’re lucky, your car’s power charger port is positioned such that you can mount the RoadTrip with a single arm, and if so, your experience with the RoadTrip will be significantly better than ours.

Try as we did over the course of three days, we couldn’t place the RoadTrip in a position that was both viewable and avoided bumping in to one of our test cars’ gear shifters when it was moved, and the closest we could get was when both extension arms were attached. The RoadTrip was even less easy to view in our other test car. While this could be blamed on the positioning of existing components in our test vehicles, it’s actually more the fault of the RoadTrip’s oversized cradle (6.5” by 2.5” x 1.7” with 3G iPod attached), its dangling FM transmitter, and the design of its extending arms (which add 5-10” beyond the cradle).

Notably, some iLounge users reported similar problems in positioning DLO’s TransPod, and we note that while one of the two extension arms from both products is the same, DLO’s second arm is more adjustable than Griffin’s. In other words, if you’ve tried the TransPod and had a positioning problem, the RoadTrip is not likely to be any better. It could even be worse.

An added problem was that the combined weight of the RoadTrip cradle, the transmitter, the attached iPod and the belt clip were enough to make the double-extended contraption rock slightly to the left and right while we drove. This was despite using some nicely implemented, easy to adjust screws to tighten the locks of the multi-positioned extension arms; the weight of the RoadTrip was just too much to keep totally stable when everything (even when used only with an iPod mini) was attached. The problem decreased when one of the extensions was removed.

As a fifth and final design point, we’re not sure that other people will like the idea of using belt clips as iPod mounting devices for the RoadTrip.
