I just bought an 02 LS430 (yay!). It still has the original version that came with car. When I upgrade to the 8.1 version, besides updated maps, will there be any interface/feature enhancements other than nav? Maybe in the audio department?

Thanks!

 

Just map updates. No interface improvement. Too bad as that would be nice to be upgraded to what all the newer lexus' have.

 

Thanks for the info, to bad.
