Hi Ey_Vaz
Have you ever changed the setting in the Iroad application called “IROAD BLACKBOX Viewer” in there you able to make the change in the video quality. After you have started the program on the top you’ll see what looks like a gear circle with edges that stick out. In order for this work you need to have your Micro SD card plugged into your computer for this process to work. Click on that you might see the following “Select Configuration Path” that’s fine click “ok” after that a pop window will appear select the “Black Box” and click “ok”. You’ll see the gear on the top left and next to it you’ll see “Config” in the second row going down you’ll “Record Frame” select “Max” if “Min” is highlighted in yellow. In this menu you are able to change the following “ Record Frame, Voice Record, Volume (that would be the greeter when you first power on your car or when she tells you the replace your SD card), Effect Sound, Shock Level, Motion Detect, System Time (Im still having an issue with this part), Time Zone, Voice Language and system info ( so you can what is the latest software installed in your dash mount camera). I hope these suggestions are of use to you and everyone else whom may need em.
