Guys, all of you with issues, do you have the camera hardwired into the car ?
Did you do it yourselves ?
The reason i ask is because i noticed something interesting whilst working on my car recently. 12v isn't always true 12v .
When looking for a 12v source in my work car ( brand new Toyota Hilux ), i noticed that some wires were showing down to 11v.
The only explanation i could think of is that i was reading a signal voltage as opposed to a supply voltage. With newer cars having several computers, it is possible to read a signal voltage going from one computer to another. This may be enough to power up a low current device like the X2, but will most likely cause functionality issues.
The other possibility i guess, is that in older cars either the circuitry or the battery are showing their age.
1 - make sure you use a reliable ground reference point. The chassis of the car is best.
2 - When looking for a 12v source, ALWAYS make sure it is true 12v. What i mean by that, make sure it gives EXACTLY the same voltage reading as if you were reading straight from the battery. If it differs by as little as .5v, it means that there is voltage drop. DON"T USE IT as it is being affected by something else. This is tru for both B+ and ACC . They both must be true 12v ( battery voltage ).
If you wanna test this theory, run a temporary cable directly from the battery to the X2, at least for the B+ cable. The ACC isn't as critical as it is a signal wire, only telling the X2 to switch over to driving mode.
See how you go.
