sandygarf Posted July 26, 2018 Share Posted July 26, 2018 I have a 2014 RX 350 with 2013 maps. There is a map update screen that asks for a DVD or USB drive to update the maps. How can I find out what generation Nav system I have and/or what DVD I actually need. Please help Thanks Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted July 29, 2018 Share Posted July 29, 2018 A 2014 RX has a generation 7 navigation system with its maps stored on a hard drive. Updating it requires buying the appropriate update activation card and having a Lexus dealer do the update. The document at the following address shows how the dealer does it for the fall, 2017 map update: http://www.revbase.com/BBBMotor/TSb/DownloadPdf?id=202375 The Lexus dealer tech enters the activation card number from the card you purchased during the update process.
