When I recently received my 2007-08 nav CD which is for the 1998-2000 LS and GS cars I was impressed with this new feature:

"EMV Clock Adjustment (GS 300 Only)

The clock in this system can be corrected using signals from the GPS"

This looks like its just for GS300 cars so i won't be able to take advantage of it in my LS, but I was impressed they are still developing things like this for a 10 year old car. Not bad at all eh ?
