My man,

I just picked up a 2018 Limited few months ago and needless to say I dislike the head unit. This is coming from an '07 owner so I'm already looking into replacing the head unit with a Pioneer or something like that. The Entune thing is so annoying and the nav. system is not the same as Google's so the routes used by the nav. is longer vs routes inputted on a smartphone using Google's or Apple maps. At that point I realized I'd need to upgrade the head unit eventually.

I'm not surprised you're having problems with yours, the head unit is a POS. I respect Toyota for wanting to stay true to 4Runner nation by keeping majority of controls old-school but they could have done a better job on the head unit but that was before I found out they already had a solution in place for next gen 4Runner!

You should probably do the same if you plan to keep the truck long-term instead of a few years of leasing.
