2014 UL with HDD navigation here. Is there a way for me to update the navigation system? The screen says to insert a DVD or USB. I believe I was told the HDD version is the better one to have?

 

I had the dealer update the maps on my 2015 nav. As I recall, it was something like $350 including the minimum one hour of labor. I hear rumors of people finding some way of updating their own but I am not sure which years that applies to - or how widely available it is. Bottom line: I recommend just letting the dealer handle it.

There is a fair bit of discussion about this in various threads. I would run a search and you will find a great deal of information.

should be able to buy these anywhere from $160~$200. very easy install, please don't go to the dealer for this.

EDIT: please keep in mind the instructions above is for 2015 ES, 2014 might have different version nav unit, please research that first before buying a nav upgrade.

 

For the Generation 8 navigation system (2015 and 2016 ES) and the Generation 9 system (2017 and 2018 ES), the map data is stored on an SD card, but for the Generation 7 system (2013 and 2014 ES), the map data is stored on a hard drive, and I'm not sure whether the hard drive can be updated other than by the dealer.

 

Get the navi maps from the Lexus dealer.

 

You may want to try searching on eBay. A friend of mine recently got map updates from this seller: ebay.com/usr/mapcarua

He seems to be happy with the purchase.
