SL/R231: Latest Nav Update?












You download the maps to a USB drive (speed depends on your bandwidth) and COMAND recognizes it when you plug the USB into the car. It takes about 1/2 hour for all North America maps to update in the car.
As far as I'm concerned, this is a major feature of the 2019 models.




Thanks much.

First, OTA only updates one region while download allows you to update all of North America. This is important if you take any road trips. Second, OTA update can take months to get to your car while download is now. And finally, OTA does not update the voice files, so it's not really a complete update. To get the pronunciations of new additions, you have to do your own.

With a Manual Update, I am having trouble... the MercedesMe Download Manager does not recognize my USB storage which is a 60GB memory stick formatted as ExFAT. No luck with restarting my iMac to see if that helps, so it seems that I am up that famous creek for a manual update.

Hmm. Unfortunately NTFS is not an option in Apple's Disc Utility and I don't find an application for this on Apple's App Store. I did install and use Tuxera's Disc Manager to format the memory stick into NTFS but the disc is still not found or the MM Manager is hung up searching for it.
As you suggest, I'll either have to use a friend's Windows machine or rely on the auto download or the dealer installation. Thanks for your help.

't't




And Whoover, you are correct -- the over-the-air only updated my region, not the entire USA, Mexico, and Canada. The download covers all this, including Alaska.

Unfortunately in the '19 SL550, it appears that only the dealer can update the map. The memory stick inserted into either USB port in the center armrest was not recognized. The version recently installed by the dealer for Western States is "2020 V13.0." I do not know if updates for other regions are available. You can check your version from the COMMAND menus -- in Navigation to to OPTIONS/MAP CONTENT/MAP VERSION.

I'm interested in updating the NAV S/W on my 2017 Merc SL 450. From reading this thread it appears that the owners of 2019 and newer
R231's are able to install the NAV updates via USB. Since 2017 was the first year of the R231 model update I'm concerned that the 2017 and
possibly the 2018 may not be able to update the NAV S/W via the USB port. I tried to order the latest update from an online company called Mercedes
Navigation Updates. When I tried to enter my car's model year only years 2013 through 2016 were offered to choose from. I'd like to hear
from 2017 SL 450/550 owners who have actually updated their NAV S/W via the USB port - did you encounter any problems with your update?

I recently updated my 2016 SL 400 myself with 2020 Mercedes NTG 4.5/4.7 Navigation Update V20. If you are handy with a computer, you just upload the map update to your computer, extract to a USB (needs to be formatted correctly) and then insert the USB in the car. If you have done everything correctly, the car will recognize that you are trying to update the maps and ask you for a key (which you can then get from this company that sent you the update). There are helpful videos explaining the process, or you can get a preloaded USB directly for a slight upcharge which saves you some time with the computer upload and extraction.
