Set my own navigation!

there's an option to avoid highways in the Nav settings

 

sounds like toy nav has actually gone backwards in efficiency. why am i not surprised/

 

I can't comment with respect to the P.Prime in particular, since mine hasn't arrived yet, but on my 2009 (Gen-2), I have found that:
- All in all, it usually works just fine, but
- Occasionally it does wacky crap like you're describing here, but
- Occasionally it gives me very-insightful directions based upon information that I was not aware of.

The most common problem I've had with it isn't a problem with the Nav as such: It tells me that I have arrived at my destination, and yet I still can't find it! Not surprisingly, those are cases where the destination is just simply not really well-marked from the road.

Still, there might be ways the Nav, conceptually speaking at least, could help with that:

The most-recent time that happened, it told me I had arrived but in fact I still had 5-10ish meters to go, and the place I was trying to go to was hidden behind some trees from there. I agree that -- generally speaking -- it's better for it to tell me that I've arrived a little early rather than a little late, but it appears that strategy isn't always best.

Another way it potentially could help would be if it's map included some sort of representation of the trees hiding the destination. It wouldn't have to be a full satellite/drone overview as such.

Conceptually, I could have seen the remaining 5-10ish meters on the map if I were to zoom in further. I can't remember either way as to whether I could have zoomed in further.

I do remember, however, that I tried to get my iPhone to show me where it is after the Toyota Nav said I'd already arrived, and the iPhone pretty much said the same: that I'd already arrived.


iPhone ? Pro

 

I haven't tried this yet, but the manual refers to the ability to set (and store) a custom route. You would access this through the Options button on the main nave page (11 inch display).

 

On the map in the top left corner select "option". hit that twice and there is an option to trace a route. I dont remember the exact wording as im not in my car. I was told by the dealer that once the route is traced you can select it and it will notify you of traffic congestion. I havn't tried this yet but it should be the way to get you to the destination the way you want.

 

I have similar problems with the nav system in my 2017 Prius Prime Advanced. I have been testing it on familiar routes since I got it in March 2018. It often does not take you by the most efficient route and sometimes does bizarre things, like taking you a mile past a turn you need to make and then having you reverse direction by getting off at the next exit, going over an overpass and then taking you back to your turn. I'd like to stick a Garmin over the stupid thing, but the nav screen is touch sensitive and I haven't found a place to stick it. Windshield, I guess. It would be better there anyway, because I don't like the way you have to take your eyes away from the road to look at the built-in screen. The Garmin has much better voice recognition and traffic rerouting too.

 

The Toyota (Denso) navigation avoids many roadways that my Garmin Nuvi gladly uses. This occurs on my ‘18 Prime as it did with my Gen2 back in ‘04.

 

I took a trip to Delaware from Maine this past summer and the stupid nav system had me exit the Jersey Turnpike, take a few turns and get back onto the same Jersey Turnpike. Wth??

 

My 06 needed a garmin alongside, so did my 11, and now my 17’, if you don’t know the route, use the garmin, the Prius is great for checking what’s at the next exit, but ignore it’s directions if you don’t know the route.
