Navigation Update not available

Does anyone know if, or when, they will be coming out with a navigation update? I used mine for the first time in my 2016 SRX (recently bought) and it had me going all over the place because it did not recognize all the ‘new’ roads that have been around for years. Had to pull over and bring it up on my phone instead. Not good. I found the site where you are to order the update, but just says it is not available and will let you know when it is.
