Review: Belkin TuneCast Auto with ClearScan for iPhone 3G

The Belkin TuneCast Auto with ClearScan for iPhone 3G is available and can be purchased in iMore Store for $79.95. If you are looking for a charger/ FM transmitter in one for your iPhone, this might be for you. Let's see how it measures up after the break!


The Belkin TuneCast Auto is a charger/FM transmitter that sends your iPhone's audio directly to your FM radio.  The device is made of plastic and has been quite resilient. The cord length is just about perfect. I currently plug it in under my car's arm rest and it is just long enough. The transmitter is compact and easy to use.

Daily Use

I admit it, or perhaps I shouldn't, but I am one of those people that sometimes drives with my headphones in. I liken this to the same as someone playing their boom-box loudly in their car. So, being a good citizen, I wanted do the right thing and find a way to listen to music without headphones; in comes the Belkin TuneCast Auto!

I have a 45-minute commute each way to work, so I use this thing A LOT and for extended periods of time, driving through several parts of town before arriving at my place of employment. Why is this important? Well, the way this device works is, it sends the the iPhone's audio to a radio channel that is not currently being broadcast on. So, in theory, you find an "empty" channel and you are in business. Well, like I said, in theory anyway. The reality is where I live, there are very, very, very few stations (like 3) that don't broadcast anything. What is the magic station for me? 96.1, for about 75 percent of my commute. Since I am driving from suburbia to downtown, as I approach the city, there is more and more static encroaching on the crystal-clear audio I enjoyed from my home; frustrating indeed.

So how do you resolve this? Well the Belkin TuneCast Auto gives you a few tools at your disposal. First up is the scanner. You press the button and if finds a station, based on your location, that has the least amount of static or stations to transmit to the radio. You can adjust by numerical increment if you like too. For example, the device select 105.4, but you find that 105.5 provides a slightly clearer listening experience, you can adjust at that level.

Next, you can save up to two favorite channels. This is quite helpful in my instance. I choose one channel for most of my commute, then as I get closer to work, I switch to another. It would have been really handy to have more then two saved presets, but alas, what can you do.

Lastly, you have "Pro" settings that help improve the audio performance. There are Pro levels 1-3 that essentially increase the volume of the music if it is muffled over the air with the FM reception. The last level plays in mono, further decreasing static.


I really like the Belkin TuneCast Auto for iPhone 3G. The problems I have with it are really just inherent of the technology and its compatibility in my city; there just aren't any available stations that don't have anything being broadcast on them. This issue, however, is not Belkin's so I feel it is unfair to knock them any points for this. Instead, the disappointments I have with the device are listed below, that just prevent it form being a 5-star device.


  • Hey, instant iPhone to Stereo transmission in your car!
  • Ample cord length
  • Good reception (when there is a available channel)


  • It would be nice if the 30-pin connector snapped into place to make it more secure
  • Having more than 2 presets for stations would be nice

  • I agree that you can't knock the device for the inherent problems with using the FM signal. However, in my almost 1 year of using the old Belkin smartscan with my 3g iphone I can't count the number of times I almost got in an accident trying to get a good signal!
  • I have been using this device for a while now and I agree with all the points in this article - I actually would go as far as to say the 'find a clear channel selector' is a bit of a sham, but that may be that there are no clear channels to find.
    My biggest complaint is when I plug this device into my 3G I often get the "This devise is not supported would you like me to switch to airplane mode .." message! What is up with that?
  • I used an fm transmitter for my old 30 gig iPod and found a great trick for reception. I unscrewed my antenna which let the weaker stations die out. It left me with many more stations and the popular strong radio stations still made it through.
  • The reality is where I live, there are very, very, very few stations (like 3) that don’t broadcast anything.
    I stumbled over this, until I realized that what the author meant to write is: there are very, very, very few frequencies on which no stations are broadcasting.
    Otherwise, he is telling us that there are three radio stations in his area that have decided not to broadcast any content.
  • I bought one of these for the several road trips we were planning. We didn't abuse it, but on the third trip we found that one of the wire had broken internally causing intermittent audio on the left channel. I can't recommend buying one of these.
  • paul, that is what he's saying. so you can stop stumbling over what he says. also, you can try and stop being a pompous douchebag.
  • this product is a sham. when i TRIED to take it back they couldn't get it to work at the apple store (located in Ridgeland, MISSISSIPPI) which is basically located next to open fields. you must get a check from apple to shill for this piece of junk.
    then, they wouldn't take it back at the store because my trip lasted more than 14 days.... you get the picture.
  • DO NOT BUY THIS PRODUCT!! This review is incorrect. Sure it is built sturdy and in theory is supposed to work by the click of a button. But every time you try to find a station there is not one and if it finds one it is already taken by a radio station. Horrible!!
  • This product worked really bad for me. Some days it worked perfect, then the next day it was absolutely horrible, even when tuned onto the same stations. Now the thing doesn't even turn on when I plug everything in. I don't know what the problem is.
  • Hi, i feel that i noticed you visited my site so i got here to go back the want?.I'm attempting to in finding things to enhance my website!I assume its adequate to make use of some of your ideas!!
