Hi just purchased a 2008 RX 350 C.P.O. with 18000 miles for my wife . This has navigation and am wondering about the need to update the system i have seen the update dvd for $199.00 is it worth the money will it enhance the sysytem also is there any place to get the update dvd cheaper
thanks

 

Just a few posts below this one you will see the price has been reduced to $169. The Navigation DVD is proprietary to Lexus and they are the only source.

 

Or you can just wait a couple of weeks. And get last years update cheap on eBay.
