i do not have nav. Can I get an SD card from eBay for about $100 and use that? Mine is a 2017. Thanks

I did not order factory Nav, instead I went with Android Auto.. I did not like the fact that Android take over the control, which make music from SD card inaccessible.
I searched Ebay, Amazon for Garmin SD map.. $200 +.. (found one for 175) ver 8.0 or 8.2.. works flawlessly,, later updated the map to latest..
You can also send address from MB app to the truck.. instead of clicking the address..Nice feature,,
