Griffin iTrip Dual Connect car kit for iPhone
Tune in, trip out
Accessory of the Week Sending audio from your iPod or iPhone to your car stereo over FM is all very well, but it has some nasty drawbacks.
There’s the lack of available frequencies in urban areas, for starters. And even when you’ve found a free one at the start of a journey, there’s no guarantee it will remain usable throughout your trip.
Then there’s the poor quality of the FM signal, the interference, and the all-round disappointing experience of listening to your favourite music after it’s been taken apart, flung through the air and re-assembled by a radio receiver.
That’s why Griffin has added another option to its latest iTrip: the ability to plug in your iPhone using its Dock connector and hook it up to your car stereo’s auxiliary input. Stick the iTrip itself in a power or cigarette lighter socket and you have a remote control, for changing volume and skipping tracks, too.
I used the CD multi-changer input on my car’s stereo, with a third-party cable to provide a mini-jack, which I plugged into the iTrip’s 3.5mm output.
Using the Dock connector means that iTrip handles the digital/audio conversion. That significantly improves audio fidelity, compared to plugging the jack into the iPhone’s headphone socket. I did occasionally notice some interference, however, probably because the iTrip isn’t shielded and its audio circuitry is very close to the power input.
I also found that the iTrip itself is a little loose in the socket. And, given that it’s connected by a cable, finding somewhere to put your iPhone or iPod while you drive could be trick. I would have liked a cradle to house the iPhone, though that would inevitably push up the price.
Those niggles aside, however, the iTrip Dual Connect offers the opportunity to use FM when you haven’t got access to an auxiliary input and the opportunity to listen to your iPod or iPhone in the car at a very high level of audio quality. ®

Digital audio out now on the iPhone? Really?
"Using the Dock connector means that iTrip handles the digital/audio conversion"
Er, does it? Are you sure you didn't just give a glowing review to a £40 device because it can perform the function of a £2 cable?
Is there any evidence that the *digital* audio output of the iPod is available on the dock connector, as opposed to the easily-grabbed line outs (which are not properly shielded)?
There's no mention of any built-in DAC in the website for this device http://store.griffintechnology.com/itrip-dualconnect.
Actually, for the princely sum of £19.99 I can have pretty much the perfect use of my HTC Desire S in my Jetta's Aux input with a "Griffin WindowSeat AUX Windshield or dash mount with AUX cable"
Best thing about the FM transmitter was the ability to block out the inane DJ patter of the local radio station.
The tape deck of the 1993 Citroen Xantia also had an audio in port on the front of the stereo. Futureproof.
Sorry, it is at least plausible
A bit of Googling shows that Cambridge Audio do a digital audio interface on the dock connector so this is in fact possible, although still rather unlikely on a £40 ICE product that never mentions it in the marketing materials.
Shame the pinouts on the net don't show how this digital output is accessed. Anyone know, or is this MFi-confidential? ;)
Digital or analog audio feed?
Does it really pull off digital audio and have its own D/A converters? The dock connector has both digital and analog feeds but my experience is that most docks etc. use the analog.
