Navigation Update

How do you update the navigation system so you don't keep getting address not found?

I see this is your first post and you may not know how valuable the search feature of this forum is.

Here is a thread from the past where I posted instructions on how to change out the nav harddrive in the trunk: http://us.lexusownersclub.com/forums/index...836&hl=hard

The latest edition of the harddrive can be obtained from a variety of online parts suppliers. You first might want to check the edition of the hard drive that you have. I think there are instructions on how to do this in the nav manual that came with your car. If you don't have a nav manual you can get a replacement through a Lexus dealer.

The hard drive edition information may (I really don't know) be on the harddrive itself - you could pop it out and take a look -- only takes a minute or two.

It is hard to say if a later harddrive will solve your problem. The tiny harddrive of your old nav system holds only about 1/100 of the amount of information that a postage stamp size 2 gigabyte SD card holds.
