Hmm...I wonder if Sewell Lexus would sell you one of the ones returned for a rebate? A quick call couldn't hurt anything, right?

Shoot, they only paid $50 for them...

From what I have been able to find, the 2005 Sienna is a Gen 4 system. Depending on the year of your LS430, it may also be a Gen 4.

Most sources list the Nav discs to be interchangable between toyota/lexus as long as the Generations are the same.

My LS430 is a 2004, which I think is also a Gen 4. I am wondering if I could burn a copy of the DVD and install it in the Sienna?

Thanks for the great info!!

The other option is to buy an older one off ebay or craigslist. You can get an OEM 6.1 or 7.1 disc that someone swapped out for much less if you don't need the latest and greatest. Just have to be careful to get the correct Generation.

It is a good idea but the cheapest one at eBay was $189 for a 7.1 disc.

BTW, my wife drives a 2005 Toyota Sienna. Anybody knows where to find the latest update to its navigation system?

Thanks!

Look again? $250 with a $50 rebate? No tax if you live outside of Texas?

Are we spatting Steve?

The rebate is only if you have the 7.1 DVD disc that you can return to them. I have an older one (have not upgraded the navigation since I bought the car in 2004), so no rebate for me. Still, this is cheaper than going through my local Lexus dealer.

You can get the update from a discount dealer like Sewell Lexus.

They have a link there on how to install the update. It is straightforward. Remove the disc, insert the new one, wait for the loading screen to go away, select your region and done.

Good Luck!

Many thanks on the info!!

I recently got a postcard from Lexus announcing the Version 8.1 Map Update Service. They want $265 plus labor (approx. $50 at my dealer). These are my questions:

1. Are these reasonable costs?

2. Can I buy the upgrade and install it myself? Is it a technically challenging installation?

3. Are there any other reliable sources of this software other than Lexus, at a significantly better price?

Any help will be appreciated,
