Can I install the official Prius Nav system after the fact?

welcome! no. but you would be better served to save up some money for a replacement h/u with a decent nav and other features. the prius nag is dog poop. all the best.

 

head unit. search around in gen 4 forums. it's still too new, but i think there are a couple stereo threads.

 

bisco, can you expand on your "dog poop" comment? My Nav seems to work pretty good. Just type in the address, and away you go. That nice female voice directs me.

And Jesse, were you looking at the regular Three model, or the Three Touring? My regular Three does not have leather (SofTex) seats. (But is has Nav and a spare tire.)

 

hopefully, they are improved. my gen II and III are much worse than a cheap garmin. sometimes i'll type in an address, and it won't take the city, or the state! the voice commands don't give you enough warning of upcoming turns. i was in nyc last week, and you really need help to know which lane you should be in for an exit. everyones going 55 in a 30 mph zone, you barely have time to think, and need more audible directions.
the upgrades are expensive, and even when new, there are a lot of streets missing.
don't get me wrong, it's not horrible, just using hyperbole, but if i didn't have it, i would get a head unit with a good rep for nav, phone, bluetooth, sound of course, apps and etc.

 

Ok, thanks. I'm still very new with it. She seems to give a 1 mile, 1/2 mile, and 1/4 mile heads up to make a turn. But the voice commands may require repeating... She cant seem to hear me very well. It seems to work best when there are preset destinations typed in.

I gotta go back and study that complicated user manual again.

 

the 700 page one?

 

Nah, the manual for the Nav is only about 200 pages. Come to think of it, I don't think I even read it yet!

 

Use your phone! I like Google Maps, but Waze is pretty good, too. The Prius navigation is good, but better traffic info is on your phone. The Prius nav doesn't use up your data plan. If you decide to use your phone, I suggest buying a phone clip stand on Amazon.

I don't now, but to me, installing the nav with the bigger screen seems impossible (or very expensive).

 

The factory nav is awful. It's 2D and slow. Buy something better!

 

I believe the OEM head unit if $5000 from Toyota parts.

You mention the price increase without to with NAV was out of your budget when you purchased.

Best, buy a Garmin or use a Smart Phone application for navigation.
(or a co-driver with a paper map...haha)

Option, there may be other head units, like Panasonic or Kenwood, that will fit the dash.
Yet I don't think you will be able to tie in with the steering wheel buttons, microphones etc.
This could get expensive if you can not do electrical yourself.
In this case we will look for another co-members insights.
