I was driving down the freeway and the nav screen died. Doesnt turn on i hope the ext warranty covers this. Its the platinum one. How much does the screen cost? They just changed the front left axle too. Took 6hrs and 2 days. Its was clicking.

-updated-

Toyota tech says the whole unit need to be changed. It's just the screen, but the part to replace IS the whole unit. So if your screen dies and you go to the dealership they will have to change the whole unit. Price? $5,820 USD tech said that is the approved amount to replace and added that it is DISCOUNTED since the ext warranty is paying for it. If I was the one paying it he said It would be more and estimated it to be around $7,000 USD.

Well, I guess the ext warranty platinum already paid for itself. Cost me way less than that. Like a fraction of the cost! 8 yr / 125K - $1505.00 2nd owner.

This is after they replaced the Front Left Axle which he estimated that it might have been around 1k. He could not get an exact figure since it had already been done a week ago.

-Another Update-

They sent me home with the RAV4 EV and it still has the old nav unit. Here is the crazy thing. Someone pressed the radio button and now, since I can't turn it off, everytime I turn on the rav4 ev the radio comes on. There are only two ways I know how to kill it so it doesn't turn back on when you turn the rav4 ev on. 1 Using the nav screen to manually turn it off or 2.- Press the home button on the nav unit so it auto turns off.

Since the screen is dead I went ahead and used the nav home button... and it worked! Now the radio doesn't turn on every time I turn the rav4 ev on. So it seems the nav unit fully works except for the screen, but the whole thing requires replacement anyway.

The dealer only changes assemblies. Good thing you have a warranty or it would cost thousands.

Be sure to check the fuses first though.

...and the grounding, and the seating of connectors on the back.

Wait, wait, wait... if it is covered by the warranty then why do I have to check the fuses and the grounding and the connector in the back? If its any of these three items will it not be covered by the ext warranty? Is that why I should check? Where are the connectors in the back? Is that in the back of the screen? Or under the arm rest? I noticed some, what look like, hard drives under the arm rest box. I did pop off the prius shifter cover and noticed, what looks like, another HD but this one under the cup holders.

I don't think it could be the fuse because the nav screen died while I was driving on the freeway and I had an address already punched in. The screen went back, but the voice prompts still continued all the way for the rest of the 30 minute drive. It was a little weird because I had to pay more attention to the signs since the screen was dead. The voice promps still worked. Is the fuse of the screen different from the fuse of the nav voice prompt system?

How much does the screen cost? You say thousands?!?! This is also for the regular gasser version of the rav4 2012? Or did we get a special screen?

If you can re-seat a connector on the back of the head unit, you can save yourself a trip to the dealer. That is the only reason to look at it yourself if you have the Extended Warranty.

The screen and head unit in the RAV4 EV is not available in any other RAV4 model. The hardware may be similar to or the same as in a Lexus model.

I popped out the two plastic trims on the side of the nav screen display, but I can't seem to pop out the nav screen. I see four? hex bolts holding a metallic bracket that seems to be connected to the screen. Do I need to remove these to pop out the screen? Also, the air vents on top... do these pop out separately or with the nav screen?

Also I was trying to use the 'talk switch' to enter and address and see if I can get some voice prompt directions with out using the nav touch screen. I can't seem to get it to send me to my destination. Do you have to press a go button on the nav screen after you use the talk switch to verbally enter the city, street name, and address of your destination?

lol this is nuts !

Have you checked the fuses like Glenn suggested?

As was mentioned, its much better to solve it yourself if its a quick and easy fix like a fuse.

To answer your last question though, if you were going to check the connection on the back of the display, yes you would need to unscrew those screws to pull the display out. I wouldnt think that is the problem but its possible.

Id check ALL fuses first.

I'm looking at the rav4 ev manual and looking at all the fuses listed for navigation. There is only one entry:


Quote:
Fuse block (under side view)

18

ECU-IG1 1

10 A

Electronically controlled brake sys-
tem, tire pressure warning system,
air conditioning system, main body
ECU, anti-glare inside rear view
mirror, Vehicle Proximity Notifica-
tion System, navigation system


That is the only entry I see for Navigation system. I do not think it is the fuse (If that is indeed the fuse for the navigation screen) because my air conditioning system is working fine and the anti-glare inside rear view mirror turns on (Green Square) and it also shines a light from its underside.

Aside from this fuse I wouldn't know which fuses to check to be hones.t I know I know you mentioned to just check all of them. I don't have the tools unfortunately so I'd have to pop them out or do it during bright sun shine (Night time right now). I think the biggest one that will be a pain in the ass is the underside fuse block on the driver side in the cabin.

Any possible suggestions on which fuse it would be if it is the Fuse block (under side view)? Could save me a cracked back and busted knees :D I know because a few months ago I blew the fuse for the power outlets. The one in the back and another that I think controlled two and getting to those fuses down under is a pain! Happened on separate occasions too.

I have a digital multimeter. They aren’t too expensive. I’d test for continuity on each fuse.

But you’d have to get a multimeter and that doesn’t help right now.

Ok then no problem. I am going to take the rav4 ev in today see what the problem is. The screen hasn't fixed itself yet, so let's see what the tech say. They had changed the front left axle because it was clicking so they shouldn't be charging any inspection fee. Not like they did before since everything was covered under warranty. Still no news on the cost to replace the screen?

-update-

Got a voice mail. It looks like they are saying that the problem is with the whole unit itself and not the connections. They called the ext warranty and got approval to change the whole unit. The part takes about a week to get here, so I guess that will be the wait time. I'll see if I can recall to ask for the price of the whole thing so we can get an estimate on how much it would have cost me. brand new nav unit hurray!
