The navigation screen is totally unusable in daylight. screen is flat and exposed to sun. driver has to lean over and hold right hand over the screen to get any visibility at all. even then you can barely see it, not to mention the danger of leaning over, using the right hand to screen, and staring at the screen rather than the road. terrible terrible design. toyota will not address the problem. $1500 mistake for anyone who purchased this add-on. you have to completely rely on the voice for navigation. *tr
When driving at any speed, under any condition, it is impossible to see the navigation screen, causing the driver to look, rather than glance, at the screen to determine driving instructions, road hazards, warnings, etc. the glare is almost blinding at times. *tr
The instruments (speedometer, tachometer, fuel gauge) of the car do not light up if the headlights are off. this can be dangerous when driving under underpasses or in the shadow of trees, etc., since one unexpectedly cannot see the speedometer or tachometer under those conditions. *tr
I bought a new 2013 rav 4 with toyota navigation. on any sunny day it is impossible to read the map due to the glare. i plan on complaining to the dealership this week. *tr
