Built in speeding warning

So far I've only had one instance where the posted speed limit on any given road did not match what my Tacoma Navigation was telling me is the speed on that road. Not all roads I drive on indicate a speed limit for that road on the center display while using the compass function though, but I'd say 90 percent are there, I also really like that if you are exceeding the posted speed, the little speed limit outline turns red. Sorry to say though that most of the time it is outlined in red while I'm at the wheel. It's a good little feature for sure. Did older versions of the Tacoma have this feature?

 

did older versions have nav?
