I swear yesterday it said 172 but today when I logged in to check, it says 193

 

If I'm not mistaken, Gen 2 hardware (early SC) is single layer technology.

 

The previous disc in my nav was 4.7GB (single layer). I made the assumption that this would be the case with the 9.1 also since it didn't have as many POIs or map details as my ver 7.x disc in my ES.

I will try to attach a photo of the maintenance screen with OVERRIDE highlighted, showing it's been selected. Car was running in park, radio off, lights off, AC was running. However, I've accessed this screen with the key in ACC position, engine off. What is NOT consistent is that the touch points don't seem to work the same every time. It takes several attempts to get into the maintenance screen. I've also attached a photo of the approx. touch points and the version screen that shows my system information.

 

To the best of my knowledge, the Lexus Nav system does not have a "speaks street names" feature. My Garmin has this feature and it is very helpful, (and also somewhat amusing when it mispronounces a street name)

Any thoughts on why a "speaks street names" has not been incorporated?

By today's standards the nav systems (gen 2) in the early SCs are somewhat minimalistic. The DVD is single layer, which greatly limits the amount of retrievable information. Similarly the processor and software in the early units are somewhat primitive compared to even a low-end Garmin today. Later SCs have much better systems. That said, Lexus as a company hadn't really embraced all of the available technology for its systems as late as mid-2000s. As an example, the Denso nav system in my 2006 ES330 (gen4) or my son's 2006 IS350 (gen 5) don't have nearly the level of sophistication and integration with other onboard systems as my 2003 Honda Accord did (Alpine). Every manufacturer or systems integrator makes design choices and the Lexus/Denso partnership must have determined that verbalizing street names was simply less desirable than something else. It wasn't because they couldn't do it. BTW I too have a Garmin nav unit and I find some of the name pronunciations entertaining as well.

 

VVTiBob, are you sure you got the $172 price correct? I just checked yesterday on Sewell's website on the 2010 map update disc and the price quoted online was $197 with the CL discount which works out to be just $2 off from the regular price of $199. Please advise how you got $172. Thanks.

 

See comment #33 above.

 

Per the FAQ...here's the link

If you need two copies of the Nav DVD, you need to BUY two copies of the Nav DVD.

 

^^^Well said.

 

i just got the new gen2/gen3 10.1 DVD. went into DVD and did the procedure described above. All of the buttons worked except the Override button. What could i be doing wrong? Weird thing is if, from this screen, i hit INFO dash button, and select Maintenance, it comes back to this screen and i am able to select Override and the Override button turns green, but then it hangs.

Is override so that you can enter information while driving?

has something changed with the new DVD?

please help. thanks.

 

You have to press and HOLD the override button for 2-3 seconds for it to activate.

 

Sewell wants $196+ and shipping for the 10.1 Gen 4 Nav update disc.
Big deal. They're giving less than a $3 discount. The dealer near me wants $225 installed.

 

Ray Catena Lexus will sell the disc for $199. What's the big deal about Sewell if they give a lousy discount of $3.00?

 

Is it possible for Lexus to let you review the newest update so that you can check for road or highway updates and also see what it will look like in your car? I'd hate to pay for an update only to find it is minimal and not worth the cost. Any feedback is appreciated.

 

You could always go to the showroom floor and check out one of the new models with NAV.
