That is very disappointing to hear. I recently drove a 2014 RAV4 and the outside light glare completely washes out the screen. I wonder if there is a film (anti-glare) that you can apply to avoid this?? My screen on my NAV NEVER washes out. Having that said, this wouldn't stop me from getting a '14 Limited. I really like them.
About that mini-screen in the cluster: You know it's only a matter of time before that trickles down to "lesser" Toyotas. The 4Runner Limited is about $50K, I don't see why it wouldn't eventually get it (if it isn't discontinued soon). If someone wanted have this feature, you would have to "retrofit" the cluster (fitment and especially connectivity issues would most likely kill this idea), I assume one would have to retro the NAV unit as well. (NAV unit communicating with the mini-screen). Anyway, very cool.
