Question: iPhone 4?
Document: This works good on my Iphone 4 but it does not work on my Ipod. That's why I gave it 3 stars.
Did NOT say it wouldn't work for the iPhone 4. IF YOU HAVE AN IPHONE 4 DO NOT BUY THIS!
Out of the box, this charger didn't charge my iPhone 4. The radio tuning feature seems to work adequately well (so far) but the lack of charging functionality is a dealbreaker for me. I guess you do get what you pay for.
My Jeep doesn't have a cassette player or an auxiliary outlet, so I resorted to this product.I love it, it works with my iPhone 4 and my iPod touch 4, there isn't static so that's a plus and overall I'd reccomend!
The function to play the iPod, Podcasts or any other apps through the radio works fine and always has. The charging function worked for about one week and stopped. Thank goodness the iPhone 4 battery far outlasts that of my 3G which I still had when I purchased this device.
The advertisement posted on amazon.com says this device will work with all iPhones, but that is not true. It will work with the iPhone 4, but not the iPhone 5. Even when you purchase a 30-pin to 8-pin converter, it does not work with the iPhone 5. When I contacted Sanoxy about this, they said "Who was the seller?"
All in all a good product for the price; transmits well enough, charges my iPhone 4... There are just a few bugs. The power pin doesn't insert all the way in to the transmitter/sit flush when plugged in. It doesn't feel like it's got a strong hold and gives me the impression that it could slip out/pull out without a lot of pressure.
It plays for my iphone 4 and itouch 4th generation. The price is great, however, the quality of it does not come with assurance. When you plug it into your phone, it will be very loose and it seems I had tie my phone and the cord with a rubber band in order for it not to come out while I drive.It will play and charge your phone, however the convenience is not apparent.
Works great and charges my Iphone 4 while playing, I live in Downtown Denver so sometimes it's hard finding an unused radio frequency to prevent interference but that's just the nature of this type of device. I am very pleased with it. You can't even buy a charger for what this costs the radio player is a real bonus.
I used it for a short time. Seems to work just fine. It worked fine with my iPhone 4. It charges the phone also. Sounds just like you are listening to your favorite fm station. Cord was long enough for the phone to sit on my front seat while I played music. It was a good deal for the price.
Answer: Yes sir
