Need a front spoiler for my lexus. Also can I upgrade my navigation cd to a higher one.

here is a front lip spoiler here. The picture shows an 05/06 ES, but they make them for the 02-04 ES also. Talk to Steve Ganz there.

As for the navigation, yes it can be upgraded to the last verison made for that system. Find out what version you have then check out www.lexus-parts.com to see what the latest version is and how much. CL members get a discount there.
