Radio and I-Pod Issue

Postby cmwagner » Mon Mar 19, 2012 1:50 pm



Hi

I have a 2005-GL1800-30th edition Wing. When I purchased the Wing from Honda (2nd Hand) I asked (and paid for) an I-Pod connection to be added to the Wing.

It has been working fine since July 2010 until about 2 Months ago, when I went through a "Hell of a Rainstorm" however the Radio works 100%m - and I don't know if it was the Rain or if it was me playing around

Basically what the problem is - is as follows:-

Plug the I-Pod into the bikes stereo system, and all I hear is very faint Vocal and 95% Instrumental (and that is every song on the I-Pod). I tried isolating the problem by plugging my Blackberry Phone into the Wing's stereo and it does the same, and when plugging my I-Pod into it's docking Station, it's 100% fine. So the problem is definetely with the Sound System on the Wing

I have been through all the settings on the Radio by pressing both Nobs Down and scrolling through the options. I have tried changing everything to no avail.

If there is a setting on the Wing, that I am missing and someone in the Forum knows of anything that I can try, please can you advise me.

As down here in South Africa - no-one can Help me.

Thanks

Colin

One of your cables is not plugged in all correctly.

This can happen on 3.5mm audio jacks. What happens is it ends up using the left channel as ground, and right channel as audio input - so basically what you're getting is the left channel minus the right channel. In audio, this is called L-R.

In most modern music, the instruments are placed in various places in the stereo sound field - so they are more in one channel than the other. However, the vocals are almost always placed dead center, with equal amplitude in both channels.

When you invert the phase of one channel (L-R), whatever is the same in both channels gets cancelled out. The result is that the vocals all but disappear, and the only thing you can hear is the remnants of the stereo reverb that they have added to the vocals.

The good news is that it can usually be fixed by checking your 3.5mm connections to ensure they're connected correctly.

Wow - Thanks for the Info - I have an idea of what it is that you are telling me.

If I understand your Reply correctly, all I have to do is open the Left Hand Side Compartment, follow the wire (that Honda fitted for the I-Pod) and make sure it is connected correctly !!

Thanks again

Colin

I would definitely trace the cables out and make sure everything is good. It does sound like the issue is between the Ipod and the stereo. Good luck.

Here's my poorly-drawn diagram of what could be happening. The first picture is of a 3.5mm male plug, and where the connectors are located.

The second picture is of the male plug inserted into the female jack, and how the spring-loaded contacts inside the jack connect to the male plug.

The third picture is of the male plug overinserted into the female jack. As you can see the jack's ground is now connected to nothing, and the plug gets an L-R signal instead.

Wingadmin, At first I thought you were drawing a picture of your knife collection... :lol: But seriously, they do a good job of explaining.
