iPod sound quality Aux input vs FM transmitter

I use my ipod though the aux cable connected to the radio. Quite by accident, looking for a useful mount for the HHR, I tested an FM transmitter and I found that with the volume set the same on the radio and iPod, the transmitter was significantly louder than the signal through the Aux input. FYI I have a variety of cable lengths (6 feet, one about 2 feet and one less than one foot) and irresepctive of cable length the volume is much lower than with the FM transmitter.

Have others noticed this? I am curious if this is typical or maybe an issue with my aux input.

I have a 4-foot or so cable from Radio Shack that I use. I haven't tried the FM transmitter yet.

The FM Modulator will give better output in levl but around my area it's hard to find a frequency that is free of interference. That is why I use the cable.

Using the aux input, I have to have the volume of the ipod almost to max. So I don't think anything is wrong with you unit.

I use this: Belkin Part # F8V7058-APL-V15

I looks like this...


I plug the "LINEOUT" from this belkin into the head unit for a better
stronger signal, and get free IPOD battery charging as well...

I have used both and with the FM mod I got a LOT of static in the music. Felt like listening to the radio and NOT a CD. I use a cable to the aux input. Sounds no different to me than putting on a decent set of earphones. I have used the setup like above and have also used the iTrip FM mod. Both suck IMO. Use the cable. Its cheaper than the modulator too!

Yea, the static was a big drag for me as well, But in my work truck, it is
the only option. For the truck I use the DLO FM thingie. I may be able
to find and post pics later. It is a really good device, and actually works
very well. (Except for the static.)

In our HHR, the cable from the Belkin still produces a better signal to the head unit than the headphone jack. It is the same signal you would use for your home stereo system.

As has been said many times before, "To each his own!"

BTW, in my area, the static is pretty bad, as there really are no "FREE or OPEN" FM points anymore. And the radio stations simply override the FM signal from the the FM transmitter.

Looked at the cables at CompUsa. Anywhere between $13-$20...rediculous. Bought a 6 footer from Radio Shack for $3.99. Haven't tried it yet though.

Well I bought one of these...excellent product and makes it easy to match the volume of the radio stations.

Now, what are you guys using as a cradle to hold the iPod and where have you placed them on the dash?

Cool Belkin

I have the Belkin 3.5mm cord, which is the same one that is pictured on chevrolet.com...I find that I have to max out the volume on the IPOD, but like 1BadPig I have an issue of finding a frequency in my area that is free of interference, so the FM transmitter is useless to me...

I would like to look into the new 'Personal Audio Link' from GM though, my dad is the parts manager at a GM dealer & supposedly you will be able to control your iPod directly through the radio, even see the names of the songs on the screen and change songs by using the steering wheel controls...sounds SWEET...
