Finally figured out my BCN last night, for the life of me I couldn't figure out how to download areas for offline use.
got BobT's maps all installed and was able to select the area I wanted to download for offline but had no options to download.
ended up watching a video on Youtube to see if I could figure it out and after selecting the area to be downloaded where the button would be.
selected my area and just clicked in the area where the button should be and it started downloading.
pretty frustrating when it didn't show the button lol
