Document: item came on time but defective, besides the defective parts its very cheaply made no connection for steering wheel controls and poor sound guilty cant tell you abou the other features because i wasnt able to use it i would keep the item if not for the defective parts,btw your going to need wire connectors because its not an exact fit like it says not to happy
Delivery was sooner than they stated. The picture on the DVD and sound is much better than the factory system. This went into a 2011 camry with a jbl factory system.Had to buy a PAC adapter and tried to install it myself but ended up having a professional do it.It was worth it to have them do it. Steering wheel volume functions still work.Pro- great overall systemCon- the manual is very unclear
It was not even neccesary to cut any wires. Without any detailed info, it took several hours to complete the installation. I would recommend this item, however, the average person may want to get it professionally installed.
Got this for the good price. I was pleasantly surprise to get it and does exactly what I wanted to do and more very good looking easy installation. Looks and work amassing very high to recommend buying this product
I ordered this item from Newerstone and received a different product which was awful.
Just installed this unit this morning after watching a video on YouTube, I decided to try it myself cause it seemed easy and it was. It took me about 3 because for 1 there was no instructions on how to, so I had to figure it out as I go. After figuring out what when where, I will say it was not that bad. I thing the hardest part was figuring out how everything works and how to adjust the settings which I am still figuring out.
Beware that you might not receive the same product you ordered from Newestone and the seller will insist/promise the item is the same quality. Don&#8217;t take the bait as I did
They installed everything perfectly. GPS works great, and its up to date, too! The Back Camera is too big for my taste, you can see it on the license plate, I wish they could have done it just a little smaller, but when put in Reverse, it changes right to the camera! I put on a CD which is the DVD, but haven't played a movie. I personally think the sound sounds a little better that it did.
The appearance looks different it won't effect any function use, you can compare with the website picture again it still have gps sd usb connector. if after install function cannot work normal, we will pay the return shipping fee and pay the install fee, is it ok? install very easy just plug and play.Well, I uploaded a video [...]  I contacted Amazon and informed them of sellers scam and I was refunded the amount of the purchase.
What I went through was just the most intolerable thing a person should have to endure if it wasn't for you Amazon purchase agreement I probably would have went after the company I warning all customers to beware of this item it looks great but the issues is to much to bear and I blame myself also because I read the other testimony and I said it can't happen to me go figure always use you first judgement
Answer: I had to play with the settings several times to get the steering wheel controls to work.
