I just purchased and setup the GNS 430/530 with data from realnav and I just wanted to make sure I am not experiencing issues with my installation.
On the NAV section map screen (second screen from the left), the CLR button does not work. I should be able to toggle different map layers by pressing the CLR button. For example roads, different airspace, etc... It should get progressively less detailed with each press until it cycles around and shows everything again. Right now when i press the CLR button nothing happens and as such i cannot see the boundaries of any airspace other than class B.
The CRSR button does not work. I should be able to press this button to get a cursor, and then twist the knobs to move it over different airspace to see the information about the airspace. The CRSR button also does nothing when I press it.
Is there something wrong with my installation or is this functionality not included. I searched the main website but couldn't find any documentation on these functions. If its not included it makes the GPS pretty useless for VFR flight, which is what I am currently using it for.
