I just downloaded the i phone version of this to just look around until my unit comes in, and my question is what do the lines and numbers on the lines on the map mean?

Should be depth of the lake above sea level at full pool, and 1' contour lines.
yep the lines are the contour and the # is the depth
That app is pretty good too, as with any map card or app you have to adjust to the actual water level of the lake. The phone app I think is in 3 foot contours and that may depend on the lake you are looking at but it will show drops and creeks and rivers very well.

(Note: on my iPhone Navionics app of my home lakes of Ky and Barkley lakes...the numbers attached to individual contour line represent the water depth at that specific contour at the specific time that Navionics mapped the lake...which means each depth number will change with rising and falling water levels...)

I have it as well. Be careful, it'll drain the battery quick.
