Took a long trip over the weekend and found a problem with GPS
On the main navigation screen which shows your route the time to destination in the bottom right hand corner does not update unless you do a reroute to the same location.
Also it seems like when calulating time it doesn't take speed into account...
i know the default lexus gps does...shouldn't be a safety issue
I also noticed the same thing, it seems that it does update periodically, possibly when you change highways, but it is not nearly as often as I would like it to.
I took a trip to houston from kansas city. Streetdeck performed great for the most part with a few glitches. One of them being the update remaining time.
