We test drove a 2014 QX60 and my wife was surprised at how soon the front camera view changed to NAV again. Is there any way...even an after market mod...that would allow them to stay ON? During the start of the test drive she bumped a small curb getting out of the dealers parking lot. No problem, but it would be nice if she could have kept it on longer before it switched. Isn't that the whole point of these camera(s)?
