E06 Driving Recorder Car Camera, Rear View Mirror Car Dash Cam 7.84" 4G Android 5.1 Wifi Bluetooth Rearview Mirror Car DVR with SIM card slot G-Sensor Loop Recording

It is worth the money but it is not faultless. If you expect perfectly functioning device this is not for you.- Streams well music with 4G SIM card and trasmits it to radio. Except when it crashes.- Google Maps works.- Easy to flip back and and front cameras and dual view works.Not impressed with stability.- Occasional crashes. More than one per day. Reboot is easy and then it works fine again.- Refuses to recognize sometimes SD-card. Mine is very fast Kingston 32 GB Micro SDHC UHS-I Speed Class 3. Maybe it is incompatible? After reboot it recognizes the card again.Back camera image quality is poor. In low light it is very poor, almost useless.In spite of countless attempts I was unable to install the phone app. I have an Android phone, Huawei P8 Lite. Tried many ways, always complains that SD card is not installed and then refuses to install.It automatically locks crash video. I had to set sensitivity to low to avoid frequent video locking. But I have not found a way to lock manually current or previous video - when somenthing worth saving happens.When it works it is a fine product. Many useful settings. Nice packing. Due to stability issues 4 stars would be too much. I settle for 3.

Responsive Android smart mirror functions while still open for new/updated apps to be installed via 4G or WiFi Internet connection. Some factory installed apps might need to be updated but fully functional afterwards. The ADAS supported features are working decent, DVR function works instant and flawless, monitor parking is long enough served by the internal battery juice (it really surprised me how fast is re-charging once re-powered via its own cigarette lighter connector), remote view and recording works well if you have installed the 4G sim card. Note that no internal phone or messaging function depends on the mirror 4G sim card account but on your smartphone one instead (subject to pair it via Bluetooth). I have installed Netflix, Amazon Prime Video and Music and all seem to be supported and streaming & scalling well on the mirror LCD screen (you might need older versions of the apps to run on Lolipop 5.1). The FM transmitter sends excellent quality sound to my Lexus audio system (it surprised me again as the first FM transmitter to work without noise/hissing while still Hi-Fi bass & trebble), Waze requires re-installation to work (some Chinese version glitches otherwise), Amazon Alexa and Reverb for Alexa are working fine - in overall a great all-in-one functional gadget to help and entertain you while driving. Just need to test its resilience now (across the extreme winter and summer temperatures). Highly recommended!
