iPhone 3G Car Charger

I have two Griffin PowerJolts (one new, bought with the 3G, one old one, pre-iPhone), both work fine with the new 3G iPhones we have.

Ok, that provides a way to charge the iPhone 3G; what about a line out? Belkin's Auto Kit for iPod charges and provides a stereo line-out at the charger (for stereo line-ins, tape adapters, etc). The line-out part works on my 3G, but the charger doesn't. Any confirmed working 3G adapters with a line-out?

I have a nice little power supply that I plug into the lighter plug. It has 2 electric outlets on it, and cost about $60 at radio-shark. This let me charge any electronics I want, use my laptop without draining the battery, and is useful while camping. This is much better than getting costly car chargers.

Although a little on the expensive side, if your stereo has RCA input, the Apple Composite Cable for iPod (with USB, and 3 RCAs) should work a treat.

The tunecast from Belkin actually works:

When I plug it in I do get an error message from the iPhone that it is not designed to work with the iphone, but it does charge it and broadcast to my stereo. It also reccomends to put the iPhone in airplane mode so that the 3g does not interfere with the signal; however I found that it works pretty good with 3g and wireless on.

You're saying just to ignore the warning -- that it in fact does charge the phone, and you can still get incoming calls hooked up to this charger?

I got the same message and believed it...

The charger charges the iPhone, and the iphone plays on my stereo with 3g, bluetooth, and wifi enabled. I get occassional interference, but it is generally from surrounding businesses and not from the phone. I get 2 warnings one says "This product is not designed to work with this phone" and the one about the possibility of having interference when broadcasting to a stereo so switch to airplane mode. I ignore those warnings and use my iPhone with my stereo.

Griffin Power Jolts works fine with mine

I have a ZipLinq car-to-USB device that would not charge my iPhone using the Apple cable. I assume this was due to its not delivering enough current. So I got an XtremeMac InCharge Auto (who thinks up these ridiculous names anyway?) with removable black ⚠ USB cable. It charges the phone, and I can plug other USB devices into the car adapter and use the cable with a computer... the best of both worlds. And I like the black cable, since I can leave it plugged into my car without screaming iProduct to anyone who glances in.

meritline has several dual-USB car chargers, but they aren't specifically rated for the iPhone.

I need a low profile car charger to use with my iphone 3G. The clearance in my console is very tight so I need a charger that will allow me to close the lid. Anyone know of a source? I understand that the special cable provided with my car, 07 BMW335i, that works with an ipod to both play music and charge the ipod will not work with the iphone 3G. Thanks.

For anyone else wondering, I just bought a Griffin Tunecast today and it works perfectly. The iPhone 3G fits in the docking station fine and the aux in and charging work.

When you first dock the phone it tells you it isn't supported but if you just ignore that warning it works completely.

Anyone reading this thread should be able to figure out that Griffin is the way to go hands down. I'm using a Power Jolt SE to charge my 3G iPhone. I have a Belkin, which stopped working for no reason (not the fuse), so I recommend staying away from Belkin.

i have the same problem. my guess is that Apple in its divine wisdom decided to take their "unauthorized accessories" thing to a new extreme and level of annoyance. It's definitely a software issue because it works on the 1st gen iphone. i loved my set up with the 1st iphone because it was basically an integrated system in my car. Apple should correct this egregious error with an update.
