Two iPhone FM Transmitters Tested
drive to the grandparents for Christmas. I bought a few from iTunes
for my iPhone but needed a way to play through the Prius stereo which
will require an FM transmitter.
An online search was disappointing. No official FM transmitters are
available. I pressed my luck and grabbed two from Radio Shack with the
following results.
Monster iCarPlay Wireless 200 (FAIL)
$49
Some other iPhone owner blogged success with this unit. I had no such
luck. It has to display the FM band on the iPod screen. This did not
happen on the iPhone. Even when I blindly coupled a band to my radio
(part skill part luck) switching from tune mode them just disconnected
it again. This unit just won't work with the iPhone.
Griffin iTrip Auto Universal Plus (3.5/5 Stars)
$49
As the name suggests, this unit is designed to work with any device
and so plugs into the headphone jack. And it fits the iPhone headphone
jack without an adapter! Yea, I hate those. Plus it has a USB port to
power and charge the device. The tuner is fully digital with 4 memory
slots and a backlight that automatically turns off.
This unit connected with no trouble, and setting was trivial to figure
out. The sound quality was average. I set the iPhone volume at a bit
less than full volume to stop sound clipping, forcing me to turn up
the radio volume. Well the sound was ok. I used the treble boost
iPhone eq setting to improve the audiobook sound and we enjoyed 5
hours of books. The backlight was perfect as as had to switch FM bands
a few times along the trip to avoid interference. Unfoutunately this
unit seems under powered and so we had to fiddle with the transmitter
position frequently to reduce static. We never got a perfectly clean
signal. All in all it worked fine for our purpose and some music
testing put it at usable in a pinch. I'll keep using it for now but my
recommendation is 3.5 stars due to the imperfect signal.
I'll probably keep looking but this is a decent option for now. Merry
Christmas!
