After some googling around, i could'nt find a good guide about converting videos to our headunits.

For my AVH-X8400BT, the manual states:


Im Using ImTOO Video Converter Ultimate 7.8.5.20141031.
First, open the program and change the conversion profile:

Then we need to make a custom profile so the program doesnt need to be setup each time(The resolution and bitrate may differ from our devices, this works very well on my X8500BT):

Now just add your videos and start the conversion, after thats done you just place them in a folder on your SD card or in my case my 60gb SSD in a HDD case, plugged in to the HU
