Question: Can you play music from an iphone 4, 4s, or 5 through the USB port?
Document: Audio is great. I love using the SD card to play my music only problem is you have to open the face to change or insert sd card. This is why it is 4 stars instead of 5 stars. If the sd slot were on the outside so you didn't have to open the face it would be fantastic .The physical installation was easy. Doing the wiring was easy as well.
IT's ok for MP3 use, don't think the radio is something here, the stations are a mess you barely can get signal in some areas, where other radios get full sinal using the same antenna, but the mp3 playback is great, the features are excellent, what i think is, for the price and the MP3 features i'll give it 4-5, also the 3.5mm output is a great addition because other people in the car can set their own music if they want
The only thing keeping me from giving this 5 stars is that when I use the AUX connection the music will not go as loud as the radio even with volume being all the way up on my phone. Other than that its wonderful. I am running it to 4 Pyle speakers in my '96 Mazda and I am very impressed with the power that I can get from this receiver even with no amp it comes through loud and clear. As I said if the AUX was louder then it would have 5 stars.
It also comes with a nice padded case to prevent scratched and damage.4) USB port - Instead of burning MP3 disc and then being too lazy to burn another one for a year, you can just throw your flash drive in there.Cons:1) ID3 tags - You only get to see a certain amount of characters on this deck, and it defaults the artists name first. This means if a file has a long artist name, you won't see what track you are on.
this radio did everything i wanted it to do. as soon as i put in a usb it automatically started to play the music on it. i havent used the sd port yet but i dont think it takes the small sd cards you use on your phone. the remote comes with a battery and the radio comes with wiring harnesses. i especially like the "loud" function because it added even more bass.
I used the unit in a camper that is in an area of little radio reception. It plays very crisp sounds and worked without a problem the first time I used it. There is no hum from the converter of the trailer which is much better than the one that was in it to start with.The radio works ok with the limited reception.I would recommend this unit to anyone that is looking for a device to play music using a USB drive.
I like MP3 opearation from USB drive (just like Kenwood). It is a little annoying that it doesn't play folders in alphabetical order but plays them in the order they were written onto USB drive. Shipping was awesome from Amazon and stereo was easy to install. Stereo is fairly easy to use. And like I said, stereo is ok and good for the price. If music is important to you (like me), you may want something with a little more power...
There's probably a way to get it to copy over correctly. If you know, leave a comment. I'd like to know.I'm going to keep the unit now. The music sounds good, the radio seems prone to interference but it mostly works, and the AUX IN works as expected. It would've been nice if Pyle included a paragraph in their manual about what format and computer specs the SD Card/USB Stick requires in order to play. Oh well.
i have  Pyle PL6984BL 6 x 9-Inch 400-Watt 4-Way Speakers connected to the stereo sounds great. i have it installed on my 1981 firebird Trans Am. Waiting for the Pyle PLG3.2 3.5-Inch 120-Watt Two-Way Speakers
Bought two units. One for each car. Installed first unit in about an hour and hooked up to existing speakers (4 x 6.5&#34; Kenwoods) The unit sounds great with full range of tones and almost excessive bass (turn the loudness off) Max power of the unit at 4 x 60 watts is exaggerated. It puts out about 30w per channel, which is still good and clean.
Answer: It does not support any devices add media players, only as storage devices. Unless your Apple product is capable of entering a "mass storage device" usb mode, then no. Most modern phones will not be compatible without tweaking.
