I have had my N2 Pro now for a little over three years. The battery died a long time ago. The unit still works when it has power so I have just kept using it this way. Now, however, I want to do something different. I started researching VanTrue hardwire kits and found the ODBII kit that is compatible with the N2 Pro. I have read other posts on this site where a VanTrue rep has asked what the startup voltage for the vehicle is. What I am wondering is, why does that matter? The device has low voltage protection which should keep the unit from draining the battery. Will this kit work for my car or not?
