How Do I Upgrade My Navigator? 2004 Rx330


Recommended Posts

Hi there, I'm new. I've been trying to figure out how to get an upgrade to my Version 3.1 Navigation System. Do I dare buy one off of Ebay? Will the dealer sell it to me? Any advice for a starting point would be appreciated. My husband has a really cool system in his SC430. Will the upgrade be similar? Thanks in advance.

Welcome to the forum!

The navigation is updatable by replacing the navigation DVD. The best deals I've found come from www.lexus-parts.com. Its very simple to do yourself when you get the disc.

The system will look the same as it does now, but it will have all the same maps and POIs as your husband's SC430. They changed the system in 07 with a new screen and a sharper looking menu system, the upgrade won't include that.

Take care!
