I got a Hook4 Nav+ a few months ago on closeout and installed it, but haven't done anything with the Nav+ feature, and thought I'd get started now.

 

I'm new to finders and Nav+. Does the Nav+ feature just mean it supports  Nav+ but you buy a card (filled with data) separately from Navionics, or should the unit come with a card and data set already, out of the box?

 

The Hook4 manual isn't too helpful here, just shows me how to insert an SD card but nothing about Navionics+.

 

I've owned a bunch of units in the last 20 years and not one of them ever came with a card.

Okay I didn't think so but I'm new at this so just had to ask. Thanks Jig Man.

 

I have two identical finders. If I buy a Navionics+ card, can I share it between the two finders, or is the card tied to a specific device?

 

Try contacting Lowrance technical support or Navonics technical support. Upgrades are normally a download but I am not sure about the newer units.

I phoned Lowrance support and the guy says I can use a single card on multiple devices; the card isn't tied to a specific one.
