Review on 7 Inch Double Din Car Stereo Bluetooth Touch Screen MP5 Player FM Radio, In-Dash Car Audio Receiver with Backup Camera, Hands-Free Multimedia, Supports Mirror Link, AUX, TF, USB. by Tony Beale

It takes a while for the phone to start up and load the SD card. (Expected and not bad for my 64GB) However, during that time the rear camera doesn't turn on and this is the first time you've needed a rear camera right after starting the car in a random parking spot. The touch screen is not very user-friendly and therefore dangerous to drive. Music navigation isn't intuitive, and while you can view slideshows of photos and even album art, when playing music there are no album arts and the text is too small. The steering wheel controller should be seen as a fantastic symbolic gesture, dangerous even while driving on a real steering wheel. (It should be easy for any such product/device.) I gave it two stars because it reproduces music well enough for factory pickup speakers and costs half a dollar.
