7 Inch Digital HD touchscreen DVD GPS Navigation player with FM USB RDS Bluetooth iPod for Toyota RAV4

I have products from ebay, great product but I am having a small problem that I do not know why "Button light: Red / Blue / Purple / No, touch sound" does not light, please tell me how does it light up
thanks

Awesome. Set up was a breeze and the features of linking, playing , or hooking up any A/V cables to the screens was an absolute plus! We used this on a 16 hour car ride (one way) for probably a total of 10 movies (plus video games) and it worked great. Couldn't be happier!

I was shocked at the superior quality of the product; my entire family fell for the sleek looks and superior performance after I installed it and have been operating it effortlessly. it is worth every dollar. You will attest to this too.

I installed the unit without difficulty, but the audio is so low I can barely hear it three feet away, and I had to turn on the subtitles to follow the movie. I cannot find a way to increase the volume (it is already at maximum), could someone give me a good answer?

I am enjoying this beautiful Radio, dvd/usb/ipod player, it has a perfect resolution for video, the sound is Great must have a good speaker kit, better if is an 5.1 subwoofer sorround.
About the USB the only thing that i don't like is the time it takes reading the memory.

This unit has all the capabilities that you would ever need in this day and age. I have been using this unit for about a month now and it has been working fantastic. The only bad part about this unit (and maybe its the same with similar units), is that it takes forever to read the source material if you have an external hard drive. If you have an iPhone, it only takes about ten seconds for it to load and play your music. Also, the unit doesn't allow the user to update the display screens; it just allows the user to use the preloaded, cheap backgrounds.
Despite above few cons, the rest of the unit works like a charm. I hardly ever listen to the radio since I have my iPhone playing songs at all times.

I want to keep this short and sweet to give an honest opinion about the product, and to also help those of you looking to buy it some insight.
this is far better than the competition. Not only is the price better, but the features and function are better. I haven't had any problems getting this to read thumb drives, media cards, dvds, and even my iPhone works with it flawlessly.
The bluetooth is nice, but doesn't have great outgoing sound when the car is in motion. The USB port works better than I expected, and is a nice feature.
In short, not bad!

It works well so far. Navigation system is good. When it is navigating, I could listen to some music. And my family could enjoy some movis. i'm happy with this unit although i can not watch the movie then i was driving.

Built-in Bluetooth works fine and plays music directly from me cell phone. Good dvd gps player.

I installed it by myself,it is very suitable to my car .THANK U

This product is so good I decide to purchase the 2nd one as a gift for my son and also after sales support is absolutely 5 star.

I will not talk ablut all details on this unit. This is my first GPS receiver and so far the Navigation has worked great. The only small issue I have had with it is sometimes after system startup is complete it takes a minute or so before the option of using "around current GPS location" is selectable.

At first, I think it is easy to install. When I got this unit, I did not know where to begin. Lastly, I sent a email to their service and they sent back to me a link where a detailed instruction about installation is placed. Then I made it. It worked well. Thanks.
