Update 12/6/12 Well we are in the cold weather months and so far it has held up on it's own. As you know with technology car electronics get cold and take time to "warm up". I haven't had any issues with this. It continues to work since day one for those who are concerned about "defects" from other users. This is the best accessory you can ever buy for your car stereo!Update 10/29/12 I have an AT&T; branded iPhone 5 if that makes any difference to your model, but I can confirm with 100% confidence that this works with the lightning to 30 pin adapter (not the plug). I got mine from Apple as with these devices I only trust the original manufacturer for this kind of thing. It does seem to access the iPod feature a lot quicker than my 4s maybe it's just me. But I am so glad I didn't have to upgrade the harness. I can listen to my internet stream and have GPS navigation running simultaneously using iOS version 6.0. I will let you know if I see any changes with the software updates for the iPhone 5.Update 10/15/12 This is still a 5 star item. I plugged my genuine apple 8pin to 30 pin adapter cord not the plug it's about 6 inches. To my surprise this worked as if nothing had change. It even recognizes my iPod controls for the CD deck. Note do not trust copy cat production items that do the same thing for these adapters. If you see the tech blogs there is something under the hood of that 30 pin adapter that makes most 3rd party items compatible. I say most because I haven't tried everything yet. I'm very happy I didn't have to switch out the hardware in the car after shelling out the money for this and the installation. I listen to internet radio to and from work on a daily basis. This was the best investment I made for my car ever. Great job Apple!Update 10/13/12 Upgraded to the iPhone5. Only concern I have is the lightning adapter. I am getting an official one from Apple on 10/16/12. I will post my update review for the iPhone5 at that time. Fingers crossed!So this little item was a tad expensive but Amazon was the cheapest on what I found out there.Installation- Took it to my local Best Buy because I don't know anything about car installation- For my car works with the 04 Honda Civic 4 door sedan LX (Value edition) with stock cd player.- It only took them about 35 minutes to install because there were very few people that were ahead of mePros-Confirmed, works with iPhone 4s via the 30 pin dock connector-Charges & plays simultaneously-Long 30 pin cable, at least 6 feet.-Take it to Best Buy to get it installed, they warranty it for as long as you own your car-CD controls via the 5 & 6 buttons on your radio. To enable this you need to press cd/tape when conected-The most important feature to me, allows me to listen to my internet stream over 4G. Other players such as Pandora and you default iTunes player will work just as well.Cons- Price, $100 is a lot to spend on such a small unit but it's much better than spending $160 or even $700+ for a navigation system built in.- I could barely fit the cable & iPhone in the second din space (the flap down storage area)Bottom line is if you want something in expensive to add to your existing car stereo without breaking the bank this is the way to go! Very happy with the experience so far!
