New Lowrance Software Update Problem

[Grandpa1]

I just updated my Lowrance 9 Touch to the latest software. I also use Jack Baker of Great Plains Mapping maps. With the latest update I can not view Pomona lake in the vector view. The raster is there but the unit does not let you select vector view. Just a heads up until this gets figured out.
Can you revert to a previous version?

Figured out how to get the vector view on Jack Bakers maps. The menu options are different than the user manual for a Lowrance Gen2 9 Touch.
1. Select chart icon on main page.
2. Select chart options
3. Select presentation
4. Shaded relief - off (orange triangle in corner goes off)
