which is exactly what the icable does (as i mentioned above), i also have the other cable at home (as i mentioned above) and it did not charge my nano even thought they said it would, the icable did

 

I saw some that looked like they had an extra power and ground wire. This may be what charges the iphone. Cable was cheap $13 shipped. If it does not work, I will get one of the other ones with the extra wires and try it. The one I ordered looks like it just plugs into the radio, so not sure there is power for charging from the radio or needs external power source. May not get the right one, but until i try it, wont know. They said I can return or exchange it if it does not work.

Went to the site there at iwire. Very confusing info there. Some charge only some play audio only, so who knows what to believe. Will try out what I ordered when it comes in and see if it works and what it does...

 

Update: I received my cable today and it does play music using my wife's itouch gen1. It does not charge it thought. I am not sure if there is no power wiring going to it from the radio, or if it is a voltage issue. It did not say there was a "incompatible charging" thing like I have seen before with iphones, so likely there is just no power going to the cable from the radio. I was told that some newer i pods use 5v instead of 12v and that an adapter/converter may work. Not sure if this is true or not as we have a 1st Gen itouch, so it should work. I would rather have the charging option if I am going to install it, so will continue my quest.

 

That's too bad. I have an iPhone 3GS, and would love a cable that both charges and plays that plugs into the back of the head unit, and I could've sworn I came across something of this nature not too long ago, but don't see it now...

 

try this, i had one and it charged and played my nano

I think you'd have a market for that cable if you ever make it (and it's under say $60), I'd most likely not only buy one for myself, but at least one other as a present, and point it out to friends that have been looking for one!

 

What would be the best way to just get it to play music and not charge? I am leary about plugging my new 3gs into some unknown cable and frying it. It looks like the connection on the back is just an input, so most of the avail. the cables should work to just play music, but not sure. I tried to find the pin diagram for the Cr220, but can't find it right now...
