Prius (Gen 2) :: Navigation Going Out - External System Not Connected
Apr 6, 2012
My sister says that her navigation has been going out. She brought the car to the dealership and they said her entire nav system needs to be replaced. They can give her a refurbished unit for $800 + labor. The symptoms are as follows:
The screen will turn black but she can still hear the voices. The screen will come back on its own. She also gets an error message "external system not connected". She says that this could happen at any time, not just when the navigation system is being used. Also when this does happen it is as if the whole system crashes because she cannot control the AC heat and the radio goes out.
In my research i would say this was a nav ECU problem but I want to double check and so I am posting. I would like to know if the ECU from other model years can be used (assuming you carry over the same DVD version).

CD was working fine the last time I tried it but just recently when I try and use it I get an "external system not connected" message. I haven't done anything to the unit and no recent repairs.

I am not sure what kind of Prius I have. There is no MAP button on the dash. I was wondering if it was possible if there was a program I could install so I can have a GPS system.

I can't figure out how to mute the navigation system. I found the volume control, but it doesn't have a silent option. How to do this?

My 2012 PIP has the GPS nav system and if I want to shut it off before my destination I can't find out how to do it! I can't find anything on it in my Owners Manual either. I do not see a "Del. Destination" to press and I do not have a "Stop Guidance" to press either.

I have a 2010 prius with the navigation package in the last month the compass goes berserk and the the navigation gets completely lost. I have done the recalibration and it may work for an hour or a day then just start wondering.
The xm radio works fine and when I get into the system check page by pressing info while turning the light switch from off to side lights four times all the systems say they are OK and the gyro voltage and direction looks good. This problem is with the original map cd and the versionb11.1 cd.

I have the IV, with navigation. My most recent sound is from the cd player. If you open up the navigation (like your going to load a cd) it's even louder. It sounds like like a computer hard drive searching and writing data, and goes on for about 10 minutes (or longer, my patience doesn't last too long). Maybe the navigation system is uploading a database or something. No CD's vs. loading a cd do not make a difference, and the audio system is off. Weird. Only way to hear it is on a quiet night, in EV mode. Reminds me of when I used to reformat a hard drive on my old computer. I'll continue to listen for it when I pull up to a stoplight.

Is there a way to use the navigation system when you are driving instead of having to stop to key in information?

I currently have a 2006 Prius with the built in navigation. Today when I start up the car, the map display is in a repeated loop of "System Loading.... Don't turn power off".
It has been working since I got the car, and I have done a map update a couple years back but it has been working until now. Everything else in the display appears to work (Engine screen, Weather, Audio, etc).

After a long trip this past weekend, I'm curious how the navigation system gets its traffic info. I received several traffic alerts (that were all cleared by the time I got to them).

I find the home screen to be a great idea and I generally love it. Today, while using the navigation system, the system kept returning me to the home screen after a few minutes of not interacting with it. I'm fine with it doing this on the audio or weather apps, but when I'm actively navigating I'd rather it would stay on the nav screen until I hit the home button. I skimmed the settings and the manual but did not see this addressed anywhere. Is there a setting I am missing someplace?

I have a 2005 Prius the navigation system stopped working. When I press the Map button, the screen displays "the external system is not connected" also the voice came on and said voice recognition is off. Could it be a fuse or need to reset? It was working fine then just went black. I restarted the car a few times but still no work. Also where is the player at on the 05?

The navigation system always directs me to take every exit off a freeway. Should I delete all my "marks" in the system or is there something more I can do?

I recently posted that I was purchasing a low mileage 2007 Gen2 and had been told it was a base model. Actually, the seller was clueless about the options and had only had it for 3 years. Didn't know what a "Package/Type" was.
Before I got out of the driveway I discovered it did have the backup camera. However, as I began reading through the owners manual (my first operational Gen2, with a manual) and programming the radio and a few other features, I discovered that this was a Type 1 with backup camera. But soon discovered from the display and steering wheel that it lacked the Blue Tooth and Hands-Free ability. Something I have been wanting. I could live without the Nav System since I have a good system on my tablet that I take with me from vehicle to vehicle. Not sure how good the Gen2 Nav System is but have used it on my sons 2010 Gen3. Seemed ok but I'm hearing that you have to subscribe to the Nav software or is that just for updates?? Or is it just a couple CDs that I need to find??
Now that I have learned a little more about these systems, I looked at the two other Project Gen2s that I have and discover that a 2007 tired old (300k+ miles) Yellow Cab has both Nav and Bluetooth.
So, the obvious question is, are these Gen2s all prewired for the Nav System and Bluetooth and aside from the transfer of the Nav ECU from one vehicle to the other.

In June my Grandfather picked up a used 2010 Prius (not exactly sure what trim package it is? I think it's IV? It has heated front seats, voice activation, bluetooth, navigation, XM radio, NO sunroof though)
He honestly doesn't like the car that much, I don't think he knew about the "PWR" button that would make the gas pedal behave more like a standard throttle, but he is away on a trip right now so I am borrowing the car. I love it, and I'm going to show him the "PWR" mode when he gets back and see if that changes his opinion of the car.
ANYWAY I noticed when driving it that pressing the MAP button doesn't actually make the map display and instead changes the radio station? I did some searching and found that this may actually be a known flaw although from my searching it doesn't look like Toyota has addressed this?
I'm guessing the car is probably out of the original manufacturers warranty? Not sure if there might have been some sort of warranty from when he purchased the car pre-owned? I definitely plan to talk to him about this when he gets back because it is very annoying to not be able to switch back to the map easily. The only ways I have figured out to work around this is use the voice activation and say "show map" or to press the "DEST" button, choose a destination, and then delete that destination and then it shows the map.

I pretty much have my car all setup now, but one thing that I have not been able to do is receive text messages to where it will display on the in dash screen. I have the Solar Package / Premium Navigation system. As for my Phone, I have the Galaxy Note II with Android 4.1.2 (Jelly Bean) and AT&T. My phone still receives texts while connected to the car's blue tooth, and I can view on my phone, but I'm unable to view on the in dash display, which means I can't send out the quick replies either. Is there something in the phone that I need to set up?

I have a 2004 VW Phaeton.
Today, the sound system failed, then shortly after, the navigation system failed.
On the console, if I press any map/navigation buttons, the error message "Navigation System Unavailable" is displayed.
If I press an audio related button, the error message "DSP system is unavailable". I took it to a private vw repair shop and a vw dealer. What was causing the issue.
I am now headed to a vw dealer with certified phaeton tech. I looked towards fuse issue, but they appear to be ok..

This has to do with a rattle on cold startup from a gear connected with the VVT system. I have a 2010 camry that may be affected by this. It just past 60K miles so they probably will not cover it under warranty. Does the rattle get worse over time, or will it have an engine failure if it does not get fixed?

Is it normal for a clicking and ticking noise to constantly originate from the JBL audio navigation system? I've noticed this noise while the vehicle is in electric mode at a full stop. The noise is also present while driving.
I checked the 4 disc cd changer and they are empty. I usually use the blue tooth system to play the music.
