Question: Is this unit comes with the harness wires?
Document: I have been using this radio for a year now to replace an after-market radio which came with my used car. It's been working great.It fits a standard DIN no problem, and I installed the radio myself (with some help from Google). I used wire caps and cut my old radio out of the car. I would not recommend this method for those of you confused by wires - you'll have to buy a harness to go with this radio.
Great price and easy controls. Sony makes a great product. Face comes off, red lights, easy dial volume.Great sound. Amazon.
Super fast shipment. Great buy.....CD, IPOD port and USB for all kinds of electronics! Remote control makes everything super easy. Even comes with cord to connect to your IPOD!
Everything works as expected, tuner, cd, aux input and usb port kind of. This is where the 4/5 star review comes in.I have had no major issues what so ever with this product. The issue I do have is the versatility of the usb support.
This is a nice radio! Lots of options and can display the clock on the right side so easy to see the time. Works great with  SiriusXM SXV200v1 Connect Vehicle Tuner for SiriusXM-Ready that I got here on Amazon as well, so now my car set up is perfect with no loose wires anywhere and everything is nice and clean!
Typically this isn't a huge problem (I just turn the volume down). It also comes with a remote which I have never used.Yes, the &#34;next&#34; and &#34;back&#34; buttons will work with your idevices and works with the iPad mini and iPhone 5.The color scheme is red, which is convenient for me (my car's dash glows is red), but if aesthetics are an issue, this might not be the right choice.
It's easier to just turn down the volume.I will say that the sound is much better than that of my old car radio - but so what? That would be true of just about any one I bought. This one is definitely NOT RECOMMENDED.FWIW, this *car radio* comes with a remote control. What?? For the use of passengers in the back seat, I assume. I'd like it better if they ditched the remote and used the money to add another knob.
This one recovers on its own after a couple songs. All in all it's a great head unit at a darn good price, happy with it.
Its an awesome radio. Worth the money. Works perfectly with my ipod and xm receiver. Only drawback is that it doesn't come with a case to put the detachable head unit in.
And this was made even harder in that it does not show the "hundreds" digit on the time. Therefore you have to guess how many hundreds of mintues! Argg.I would recommend the unit. Though I would warn them about the cons.
Answer: It has a plug to go into the Sony radio. it has wires that go out of that plug to whatever you want. I recommend to get the plug for your car, with the same "whatever you want" wires coming out of it, and connect the two sets of wires to give you a harness with a Sony radio connector plug on one end, and a Chevy (or whatever) connector plug on the other end. Did 4 of these CDXGT56UI in the last 2 months, and would not do it any other way...  Walt.
