So why is this? Probably because some apple employee designed the iphone 3GS with common ground between audio pins and USB ground (and every other ground pin except pin 11) creating a very noisy ground loop.

If the 12v charging was still available I bet that could be used for charging without interfering with audio, but since 12v charging was cancelled you cannot charge and listen to audio without major interference from the groundloop, hence… noone produces docks that BOTH charges and sends audio for the iPhone 3GS.

I really hate apple for this major misuse of monopoly. MS went to courtfor misuse of monopoly and was forced to remove messenger, make IE and WMP optional etc. but Apple gets to force iTunes, new chargers for new generation phones etc. without as much as a single article in a newspaper or lawsuits.

I have and Double Din DVD (Pioneer AVH-3150dvd), conected with a composite (a/v) cable (griffin one) to my iphone. At first, the iphone charged, and trough the AV source, I could watch movies, and charge the iphone at the same time …
Although, I don’t have a rear usb out, so, I bought a common usb cigarrete lighter 12v (for cars), and conected to the power sorce … so all the cables (RCA and USB) would be hidden …
But now, the iphone wont charge !
But, when I conect the SAME cable in the front USB jacket … IT CHARGES !!!! And in the charger, if I use the ORIGINAL cable, it would charge !!!!?!!?!?!?!?!?!?
So … if I want to watch movies, I have to do it quickly !
The most strange, is that at first … it worked …. when we were installing back … it stopped charging ….

You guys have any experience in that ?

Sorry for bother you guys with this question … but I’ve searched all the net .. and got no answers … or similar cases !!!

Thanks in advance

I have owned a lot of iPods, I just got a new 64GB Touch 3G only to find it would not charge with any of my docking stations, car chargers or wall chargers. Why?

Apple decided they needed to make more money by selling you new chargers for your new iPods, so instead of leaving well enough alone they engineered a change in their newer iPods so they would NOT WORK with older chargers.

First I will explain some basic facts about the methods used to charge an iPod. Typically, your iPod will connect to a USB or a Firewire connection to charge. There are some other dedicated chargers that connect directly to your iPod and they suffer the same ailments I describe here and also have similar fixes, though they are somewhat more complex.

USB has one and only one voltage that it uses, that is 5 volts DC. Firewire has one and only one voltage that it uses, that is 12 volts DC. There is no difference in voltage between devices of the same type, period. So why is it your old USB charger worked on your old iPod, but wont work on the new iPod? After all 5 volts is 5 volts is 5 volts.

USB Type A connectors (as used on iPods) have four contacts, the two outer contacts are the power, one side is ground (pin 4) and the other is 5 volts (pin 1). The two inner contacts (pins 2 & 3) are the send and receive data contacts for communications between devices, for instance your computer and your iPod.
Apple engineered a new “feature” in their new iPods that looks for a signal on the data contacts (pins 2 & 3) before it will accept the device to charge the iPod. Older chargers had only two contacts in use, the outer ones to provide the power for the iPod. There was nothing connected to the data contacts because there was no reason to have anything connected to them, at least not until now. You new iPod will reject a charging device that does not have a signal on the data contacts (pins 2 & 3). This could be your computer communicating with it or simply a small voltage (2.5 volts) on EACH data contact. If it sees this signal it will accept the 5 volts on the power contacts and charge the iPod. If it sees the 5 volts, but does not see the signal on the data pins it will present a message to you informing you it will not work with that device. Bear in mind again, this is the same 5 volts that is on all the older chargers and it must see the 5 volts to even give you the message that it won’t use the device. There is no excuse for not using the 5 volts and simply charging itself.

There can be no other explanation for why they engineered this change into the newer iPods other than they wanted to purposely make the old charging accessories obsolete so they can sell you new ones. As an electronics engineer for the last 37 years I can say this with absolute certainty. I can understand why the new iPods do not work with the Firewire devices, Apple probably did not want to support both 12 volts and 5 volts as it takes separate circuitry for each one, but to work with newer and to not work with the older USB devices is in my opinion, criminal.

I would like to see a class action lawsuit against Apple for this greedy stunt.

By the way, if you can get inside your old charging devices there is a fairly simple way to modify them to work with the newer iPods if you are somewhat handy with a soldering iron. I just modified an old automotive (cigarette lighter socket) charger using this technique and it works great with my new iPod Touch 3G. You will need four 47K ohm resistors (1/8 watt is large enough, but any wattage will work) and possibly a few inches or small gauge wire.

Solder one end of each of two resistors to one of the two center contacts of the USB A connector inside your charger. If there is no room to place he resistors directly at the connector use a small piece of wire to connect the resistors and place them where there is room. Now take the other end of one of the resistors and connect it to the 5 volts outer contact and take the other end of the second resistor and connect it to the other outer (Ground) contact. Do the same thing using the other two resistors from the other of the two center contacts this time. What you have done with these resistors if split the 5 volts in half at the center point between each pair of resistors and connected it to one of the data contacts. The second pair of resistors does the same for the other data contact. This puts a 2.5 volt signal on both data contacts and the iPod will now allow itself to be charged with the device.

I hope this helps. It is not that hard to make these alterations.

Now go out and get mad at Apple for trying to rob you.
I smell a CLASS ACTION LAWSUIT!!!

Now, older dock connectors and charging devices can properly charge the newer iPod and iPhone models. Our Charge Converter clicks in between your device’s dock connector and your charger, and routes the charging circuits correctly. So your iPod can keep on doing what it does best.

If there is anyone out there who has, or know anyone who as aa 2009 Jaguar XF with the Portable Audio Interface option, and can charge an iPhone 3GS with the Scorsche adaptor it would be greatly appreciated if you could post here.

Many thanks.

Where can I find the instructions for this hack? I would rather potentially ruin the my 2nd gen iPhone then buy a bunch of new shit from them. Fuck apple. If I ruin it I’ll just go back to my 2st gen which I am considering just doing anyway because the battery life is terrible on the 2nd gen and the AT&T 3G network is a fucking joke.

So give me a link to that hack please!
