I thought it would make an adjustment based on how fast you were actually traveling. That is how my friend's Denali Nav seems to work. Not sure if your is the same but on my RX it has preset speeds. They normally are low. Example: highway 55mph not 60 or 70. If you go in and adjust the speeds so that they are more in line with the way you drive it will help. Mine still overestimates the time it will take.

I have a GX470 and was traveling about 280 miles on a trip. The distance was correct, but the estimated travel time was WAY off. It seemed like it was about double of the time it would take. For example 280 miles at 70mph showed as 8 hours not 4. Any ideas?

I have searched this forum for a good long time, but I am still confused on what is possible as far as adding an aftermarket rear dvd screen. My confusion comes from the Mark Levinson or non-ML talk. I just go with what I have. What I have is a 2006 Lexus GX470 with Navigation and Mark Levinson with the cd changer in glove box. What I want to do is add a flip down screen for the rear or maybe headrest screens instead. On the GXs with factory dvd, where is the dvd player located? Where would an aftermarket player be located? My dream setup would be aftermarket flip down screen with dvd player tied into the Nav screen. DVD player able to be controlled at Nav screen and even possibly watched on Nav screen. I have read about all of the DVD bypass stuff, but this applies to GXs with DVD already installed. First things first. How much of what I want is possible?
