I just got the navigation update for my '99 LS 400. I installed the hard drive and when I checked the map info the software reported the data as July 2004. The Lexus part number is PT219-F5CPX-01 2005 Lexus Hard Drive Navigation System Update . I asked the parts manager and he said this was the latest update according to his computer. I paid $260 for the update and installed it myself as it took less than 10 minutes.

Can anyone confirm that this is the latest map information? Is anyone aware whether Lexus or Denso will be updating the hard drive in the future? It would seem like they might as they required me to return the old hard drive as part of the exchange.

 

I thought a new one was JUST released?? can anyone confirm this?
