User reviews

Service partner was incredibly slow

Took over two months for the service partner to register and enable the product - u need a way better program. This is negligence for a brand new boat that I paid a premium price for including this product.

Maintenance section

I love the idea of the new maintenance section but every entry seems to appear twice?

No manuals

With the new update, my manuals disappeared. Update - the problem has since been resolved. It took a couple days but manuals are now back. Overall, the app is a handy tool for monitoring your boat while away. It’s nice to have the manuals available, but a little slow in loading and navigating back and forth. Other than that, I like it.
