NavTool installation

[goped]

I'm trying to install a backup camera using the factory navigation screen. Also, I read this on the website navtool.com
NavTool is video-in-motion enabled, so the video image will stay on the screen even with the car in motion, however we do not recommend doing this. My question is how can I watch a movie while the car is in motion when the only connections are too the handbrake and reverse light wire. I don't see any speed sensor wire. I know in order for the navigation bypass to work, there are 2 wires that need to be modified the parking brake and speed sensor. Does the module have something in it to bypass the speed sensor? Is this product any good? Anyone have it installed?

Some units don't need a speed input.. Mine doesn't.. I hve a 2 way click switch which cuts/adds signal so the head unit thinks the ebrake was engaged, gives u the warning spool and you hit ok...

How did you do that? I tapped into the ebrake line which is one wire underneath the handle and I can't enable the dvd movie without the ebrake engaged. How do I solve this problem?
