Question: Will the usb or aux input work for iphone 5?
Document: I like this receiver. I got it because it said that it was Droid compatible. It really isn't. You can't use the usb connection and you don't get any sort of functionality like you'd expect from an iPhone or iPod when you plug your android phone in. It says Pandora, but that only works with the apple products, otherwise, you're just connecting to the aux port and using it like a pair of speakers. I have no problem with the unit otherwise. The sound quality is great.
This model has all the features you would expect, with a few extras. Plus I found the various options all fairly easy to find and navigate. I haven't tried the Pandora feature--no iPhone--but the aux input sounds great with my droid. My only gripe (besides the lack of useful integration with android still common with most/all units) concerns the text display. Instead of words scrolling right to left, the text is shown in blocks of whatever fits the screen.
great stereo for super cheap. The colors are cool i guess, and the options for usb, sd, and aux are nice
And if you use the usb cable it charges your iPod/iPhone also while playing. This is a great item to invest in and a great start if you want to add subs and amplifiers later (which I will). As far as installment I paid a professional to do it because I dont know anything about installing electronics like this but I'm pretty sure it is easy because it took him less than an hour. I will post pictures soon, this radio is a beauty.
iPhone/USB mode worked more reliably. Not sure what is going on, but occasionally (maybe 5-10% of the time) when I plugin my iPhone 4S into the unit it doesn't recognize my iPhone and won't play music/podcasts. Most of the time I just have to replug-in the iPhone and the problem goes away, but on rare occasions I basically have to wait until I turn off the receiver (ie: turn off my truck).
Bought this for my wife's car and she loves this radio. It is aesthetically pleasing and plays radio and cd great. It was tricky to get the power antenna to work on the car with this, but I used the aux power to power the antenna and it worked.
The equalizer on this Sony is really nice. It also has a function to balance the speaker volume depending on where you want it. It seemed to work well. The lights are totally adjustable. If the USB port would have worked I would rate a 4 or 5 but the USB port was the main point of getting a new car stereo head and Sony gave poor customer service when I called. Amazon has had outstanding customer service.
If you have something other than an iPhone be careful though. You will need one of the other new Sonys. I chose this one because I have an iPhone and I wanted the newer SiriusXM tuner - the universal tuner. Sony does make a head unit that has pandora for blackberrys, androids, and iPhones but it uses the old satellite tuners. Not a big deal, but the universal tuner is a lot smaller and will work with any head unit in the future. The old tuners are brand specific.
Nice unit, I bought to upgrade another Sony so I would have a USB/ Ipod input. Works great, would buy again.
Overall, I'd still give it 4 out of 5 stars.This isn't a "high end" head unit for great audio, but if you're looking for something that can do just about everything, it's hard to argue about the price.
Answer: Hello.  No, the iphone5 WILL NOT be recognized as an ipod/iphone.  It WILL be recognized as a USB device, and play your songs, you just won't be able to navigate thru the playlists, genre's, etc.  I did not know what to do with the Aux input.  Here are the devices that are fully compatible with the 660UP.  Good luck!Compatible devices for Sony CDX-GT660UPThis unit can be connected to the following iPods.
