Did you have issues hooking it up due to the 24v system?I have the x1pro and like it. It can be left in a rear view mirror mode while driving which is what I wanted. Works well in low light and does record about 3 days worth of front and rear video on a 64gb card in good quality. Has software on the card you can run on your computer which shows gps location, elevation, in sync with the video.
You can view video playback on the mirror, though fast forward is not available on the mirror itself - only when using the computer software which is one drawback I found. Installation was easy - do need 12v though.
Any additional detail would be helpful
