    You must have the highway avoidance enabled. That's what it's called on my Garmin, at least.

    Avoidances include highways, toll roads, U-turns, etc. When on, the GPS will avoid each of those.

    That's gotta be it.
  • I have a 2004 Sienna XLE Limited, and have never upgraded the GPS software. What are the benefits and cost of upgrading the GPS software? Also, does this have to be purchased from the dealer, or are there other options?

    How do you play a DVD movie on the front navigation screen? I know this is possible, it has started to play a few times when I first get in and start the car.
  • I just picked up my 2008 XLE with Nav at a dealership in Maryland. I llive up in MA and found the best price on an 2008 down there, so I did the drive down in 2004 Sienna with my new Garmin 760 (use it in my Subaru Outback). The Garmin picked the normal route down I-95. It has done a great job with picking routes that make a lot of sense. When I picked up the 2008 XLE, I used its Nav system to guide me home - expecting to take me on an obvious route. I've sat through the LONG series of videos on the Toyota website on the Sienna Nav system and checked what was selected on the allow list (interstate, toll roads, etc.) It - again and again - picked strange routes. I got on I-95, but it kept telling me to get off on side interstates - through NYC - there is only one really good route - I-95 - it wanted to take me off to the west on Central Park Ave over to I-87 and then back to CT-15 - back onto I-95 for a little bit - then onto another side road instead of I-91 north (again the only 65 MPH straight route available and a no brainer). I left the guidance on to see if it would eventually correct - again and again it kept trying to pull me off 95 and 91. I turned on the Garmin around NYC to see what it suggested - 95 N to 91 N to home.

    I just couldn't believe that the Toyota Nav system would get it so wrong. I sat in the van tonight (playing with various new functions) and did the route preview for the 3 offered routes. I thought perhaps I'd just selected the wrong route (although it was the one the Nav system identified as the quickest). The preview function itself was great! But it again went through all sorts of side highways and other interstates instead of just I-95 to I-91. It actually suggested that a series of side roads (off to the west of the interstate) was the faster option than the 65 MPH interstate in one option. Scratched my head again - and even though interstates were in the mix, checked to make sure that they were allowed in the options.

    SO - what the HECK is going on with Toyota Nav??? Is there some sort of additional preference screen that could remedy this? This unit would get you there but it's going to take one out of the way and on slower roads with lots more turns and complexity and through town traffic. I just can't believe this system is so much worse than a $799 Garmin add-on.

    Please help if you've worked through this issue to a solution. :confuse: :cry:
  • Are you in park with the brake on? I just did it playing with a new XLE and it was just a matter of hitting display (I think - one of the buttons, I tried a few but it only took 30 seconds or so of experimentation) with it in park with the brake on.

    Are you sure, the allow-freeways and toll roads preferences were on? Was it taking other freeways or always trying to avoid any kind of freeway? Give me a start & end location and I'll try to punch in the route in a Camry.
  • mdchachimdchachi Posts: 275
    The benefits are updated maps & POI information. If you're in a growing area, the changes could be significant.

    I don't know of any other purchase options except the dealer.
  • Yes - as I said, it used all sorts of interstates - it just kept trying to pull me off the obvious routes. As I noted - I've check and re-checked that allow freeways, toll-roads, etc. was on. I went through the route again at home - checking everything again - used the preview feature to try all three suggested routes as noted.

    Try a starting point of 1000 H street, NW in Washington, DC and a destination of 100 Piper road in West Springfield, Ma. The Garmin route - and the one that would make sense would be 50 out of DC to 95 and then 95 all the way to 91 and then exit in West Springfield. The closest the Sienna system got was 95 and 91 for part of it but still pull one off on to I-87 around NYC and then took you off 95 around Baltimore - off and on and off and on if I recall the preview correctly. I wonder if the Camry system logic will be better - let us know.

    Sorry for not replying sooner. That's a long route and I'm not familiar with it so it's kind of hard for me to tell if I'm getting a different route or not. I went to the turn-list screen and, ignoring all the short-distance segments, this is what it is trying to do in the Camry (map version 5.1).
    I-295 for 31 miles, I-895 for 13 miles, I-95 for 56 miles, I-295 for 5 miles, US-40/NJ TPKE for 73 miles, I-95 for 113 miles, CT-15 for 21 miles, I-91 for 44 miles.
    The main difference that I see between this and Google maps is that that Google stays on the interstate through New Haven while the Camry takes Hwy 15.
  • I was told there is an override process used for the navigation system to allow usage while the car is in motion. Can someone please give me the process and maybe post a picture or some visual instruction? There has to be a way to get around this stoping/parking restriction and not allowing a passenger to input information or do searches.
  • 2006 Toyota Sienna Ltd. - Do you have instructions as to how to find the override on the GPS System to enable the passenger to make changes while driving?

    If you can help it would be much appreciated.
  • On our 2005 LandCruiser, you go to the Menu Hard Button, then select Volume Menu (not the radio volume) , and hit two spots on the screen that don't actually have any buttons. Three total presses, starting (i think) with the upper left corner, then lower left corner, then upper left corner again. That brings up a service menu; the item you want is labeled "override". Press and hold this, and voila! You can now access pretty much any menu item on the go, with the exception of manual dialing the cell phone from the nav screen.

    Hope this helps.

    It worked... I can't thank you enough.
  • lconeylconey Posts: 6
    Thank you === thank you. It Worked! I sent another message, but since I am new at this I am not sure that it went to the right place. Thanks again.
  • I'm glad to be of help for once. lol.

    I understand the legal reasons why they did this, but I would think it would be pretty easy to link the ability to do this with the 'Passenger Seat Belt' light that already exists. This, and perhaps a modification to the 'I Agree' screen, should limit thier liability. The sad thing is that ALL the aftermarket GPS systems let you search on the fly.
  • ateixeiraateixeira Posts: 72,587
    My Garmin does, however you have to turn on the safety mode. You only have to do that once, though.

    I agree with the seatbelt idea. The sensor is there, use it!
  • hello
    Great site and thx everyone to write
    I have 2004 Sienna Limited. As you know, I have the navigation system with ver 3.1
    Anyone know which upgrade version is work for mine??? 2006 or 2007??? ver 6.0??? thx for reply
  • I too have a 2004 Sienna XLE(not limited) and I have noticed a lot of navigation upgrade disks on Ebay. The problem is what version of navigation system is installed in the 2004 model? Is it Gen. 2 or 3 or Gen. 4? Also does anyone know the disk number for say the 6.1 upgrade disk? The number looks something like: 42XXX-0990. It would be nice to be able to pick up someone else's older update for the 2004 Sienna and live only a couple of years behind in map data. I've called the dealer and he gave me a long part number which has no significance outside the Toyota parts department. Thanks.

    I have a 2004 XLE Limited with Navi. I noticed several posts giving info on how to change the Navi feature which disables the system while the car is in motion. Does anyone know any tricks that would work on the 2004 system? Anything I can do to bypass the system so that it can be used (by my passenger!) when the car is in motion? I believe the previous posts were for the later Navi versions.

    2004 SIENNA GEN 3

    The part number on the disc should be 86271-3303X. The higher the last digit (X) the newer the version.
  • Thanks. I'll try that number and see what damage I can do.
  • You can override the system in a limited way (just the navigation controls, the radio info button for example will still not show anything until you stop).
    To override the navigation safety, follow these steps:

    1. Make sure you're not moving. The best time to do this is after you've started the car.
    2. Push Menu.
    3. You will see a button in the upper right of the touchscreen called DVD, press it.
    4. In the DVD window, press in rapid succession upper left, lower left, upper left, lower left, lower right. It may take several tries.
    5. You will see a new screen, press and hold override until it beeps and turns green.
    6. You're set.

    Note: If you are in a situation where you want to override and you have an opportunity to stop at say a stop sign, hit menu button and as you roll to a stop hit the DVD button and then give it gas and go. The sequence of button pushing will work even when you're moving, the trick is getting to the DVD button.
  • I too have the 2004 Sienna and am looking for the upgrade from the 3.1
    Did this part number work?
  • Yes and no. I know what to look for now, but sadly, none are for sale on Ebay beyond a 3.1.
  • I have a big problem and am hoping that someone can give me advice. I have an 2004 Sienna xle the sound does not work on the radio the screen comes up and states that the nav system is not hooked up when you press the nav button and the dvd player does not work. for a wile when I hit a bump in the road things would start to work. Now nothing. I took it to the dealer and they told me that it was the main computer in the back of the van behind the sub woffer. I took the back apart to see what they were talking about and just was more confisued. anything would be a great help! Thanks in advance!!!

    The dealer may be right, but if you're not under any extended warranty, you might try pulling the screen unit out and checking to see if all your cables are seated properly. The head unit comes out pretty easily if you pull up the two plastic trim pieces on either side. Something plastic that allows you to hook the edge and pull up from the top will make it easier. Be gentle. Once the two trim pieces are removed you'll see 4 screws holding the head unit into the dashboard. Remove the screws and pull the head unit up slowly and push on all connectors (there are a few). Before you screw everything back, you can turn on power and check to see if anything has changed. I've never messed with the main computer, so I'm no help there, but it definitely sounds like a loose cable somewhere.

    Yes, I finally found that number and the disk worked!! Now I'm only two years behind.
  • Thank you for the advice. Could you tell me where the main computer is located? That would be a big help also. Thanks
  • Could anyone tell me if you can have the main computer for the nav system repaired if not is their any place you can recommend to purchase a used system?

    Thanks in advance!!
  • I am looking for the location of the main computer for the radio and the nav system. Thanks in advance.
