Someone has managed to get the JV / Lane Assist feature to work in 205w.

The only difference is that you have an additional step to downgrade the 205W firmware to the US v2.80 before upgrading to the SG/MY version. The way to downgrade the firmware is the same as how you change the firmware as shown in the earlier posts.
