I downloaded the Winni Map. Simple process.

We took it for a "test drive" last Friday. I have a Nuvi 200W. It is on the list on their website of units that would "work" with the Lake Winni Map.

Pros:
1) Inexpensive
2) Shows Contour Depth lines
3) Tracks speed and miles
4) Shows and marks the "Hazard Areas" ( in my case.. the Witches)
5) Shows a black dotted line similar to the bizer charts of "Navigation Routes"
6) Shows feature names (Islands)
Negatives:
1) We left the Marina at Lake Shore Park and plugged in Sally's Gut. It found it and proceed to plot a course that started with .. "continue on Rt 11" and never swithed to a "water" course.
2) Didn't show any markers or buoys
3) No "suggested course" Thru Sally's Gut or any other location we input. (Meridith, Weirs..etc)
4) No "Breadcrumbs" with return path.

Bottom line... it's barely an electronic copy of the Bizer Chart, without the any visibility to markers or way points.

$10 bucks... not a total waste of money. Navigation aide... no way.

It may be that later models, my 200W is 4 years old, would show more detail.
The unit I have only gives me three choices, Auto, pedestrian, and bicycle. Even after loading the Winni Map it doesn't add the choice of "Boat".
I emailed Garmin tech support and haven't gotten a reply.
