Latest is version 3.0
I personally would see if Lincoln would update it 'under warranty' at no cost. or read some post on how to do it. youtube may have some videos. not everyone has an easy time updating it. (unsure about your color question in the other post)
I bought my '17 2.3 Reserve in February of 2017. It came with version 2.0. When version 3.0 came out, I tried unsuccessfully to upgrade. I ended up taking it back to my dealer who upgraded it to version 3.0 with no charge.
