thank you, denia!
I asked its problem to Livue directly, I received a answer today.
As a result of Downloading newest viewer and installing it, it is working well now. XD
My livue is not working properly.
though I configured the time, it was still on 1980 year.
Anyone who tell me solve this problem?
If you do, I really appreciate it.
I bought the least expensive one after comparing the prices of several brands.
Livue has a reasonable price beside the others.
But I have one question, anyone who tell me where is livue's battery consumption information of the car?
