Toyota Sienna Navigation System



  • own a 2002 Landcruiser. Took car for collision repair. Got car back and car would stall during idle; navigation system screen is blank except for cursor: the is no map. This thread has been heavily discussed here. Questions please: a) what is best course of action? b) side question: does the navigation system require the system disk inserted in the ECU to operate?
  • I keep hearing good things about Garmin but there are too many to choose from. I may purchase one at Costco. I think that the nav. in the car would not give me everything I need. accuracy, detailed directions, very current directions and clear voice and screen. I think the voice activated one may be nice. what else is there to look for?
    Thanks, WC4

    Costco is a good place to start because you can play with demo units.

    Interface is important, so see if you like Tom Tom's or Garmin's better.

    detailed directions, very current directions and clear voice and screen

    Detailed directions: Garmin > OEM, because it has text-to-speech and most OEMs don't or it's very limited.

    Very current directions: Garmin > OEM, because they have quarterly updates, while OEMs often take a year, some times 2 years, between updates.

    Clear voice: OEM > Garmin, no doubt, plus they lower the radio volume since it's integrated.

    Screen: OEM > Garmin, due to size. However, consider how distant the screen is. A 5" portable up close with a vent mount may be more clear than a 7" screen way up on the dash.

    That's how I see it.
  • Should an owner of a 2006 Sienna XLE with just under 55K miles expect the navigation system (not the map DVD) to last more than 4-5 years?

    Same happened in my case. Driving home from the dealership after a $300 repair and the whole system crashes - DVD/NAV/Radio/Rear Camera. Found a auto car audio specialist in after market/out of warranty fixes and they analyzed it for $60 and found the Mother Board in the NAV system failed - $700 to fix. I figure it's better than $3000 so I'm giving it a try. I'll comment back after they fix it.
  • Replaced nav with rebuilt from online source ( Cost was about $1300 plus $800 core that get credited-back when you return the original (one year warranty, they pay for shipping). My experience with this vendor was very civilized, other probably are too. You can do the exchange yourself easily in about 15 minutes (pop-out fake wood trim on either side of nav using flat-head screw-driver, 4 Philips-head screws on side of nav to remove black cover thingy, 4x10mm bolts in back to remove unit (I didn't drop any, but imagine this could be problematic if you do) -- lots of connectors in back, but each is different from the next and color-coded to boot. Needs DVD from Toyota (about $200) to boot system, but this worked first time and I haven't encountered any problem. Good luck.

    "I went to loading button instead and the JP-TSW is highlighted, I switch to US-RSW and now I have an error of unable to access program with some Chinese characters on it. How do I get back to that override screen."

    I know this is an old post...but did you find a fix for this problem? I have the same problem.

    I installed the Eclipse AVN726E Navigation (doubledin) in our Toyota Sienna XLE 2011. See blog for it on

    Amazing job, nice.

    Question for you - was it easier to install in your Subaru, or in the van? Just curious. We have a Sienna and a Forester.

    Where did you end up buying the XLE from?

    Is the in dash Navigation worth the price?

    What was the OTD price too?

    Please share as am looking for one in the bay area.
  • Hi there,

    I also had this issue come up, were you able to fix this Chinese characters issue? I was installing a latest nav DVD and in the override screen I accidentally selected Japanese nav and ended up in this mess. Please if you have sorted this out I would appreciate your response.

  • Hello folks,

    I just tried upgrading Navigation DVD in my 04 Toyota Sienna, however in the override screen I accidentally pressed a wrong button which now shows Japanese or Chinese letter and gives me error message. How can I go back to this DVD units original state? I have read about removing the battery from the Nav DVD player's battery etc but does that work? Do anybody know the easiet fix for this? If any body out there can help me I would greatly appreciate it.
