A large part of Lake Fork is shown as blue, and when this is removed there are no contour lines. I have notified Navionics. Fayette County lake on 2007 edition shows underwater ponds, creeks, roads, etc. On 2009 HD map all of the features are gone. This does not hold true on other HD lakes for 2009 that I looked at. For fishing purposes 2007 edition is much better than 2009 in my opinion. Will these features be added back in next release?
