Navionics Nav Module problem

[TangaraToo]

Trying very hard to purchase the add on nave module but cant seem actually get to purchase it (android phone).
When I go in to menu, charts and upgrades then nav module it displays but that's as far as I can get.
Anyone had similar problem and found the solution?
Thanks

Now sorted. Had to unload and reinstall app before it would allow purchase.

is the module worth having

Not played with it yet but at £1.49 it wasn't much of a risk

I have iOS version, which I guess is the same. Take care under Map Options to select the Water Level to zero. This slider will change the depth contours. It's meant for lakes where the level, and thus contours, change with rainfall.
I think you get a red warning if you alter it from zero. Just something to be aware of, of course if you want to show depth contours changing with predicted tide heights then you can do that.

is it called nav module under android? I cannot see anything called that but there is "advanced map" at £2.99. Is that the same thing?

you can usually get a preview on google apps. Try before you buy.
