Hello:Has anyone observed issues with the terrain mapping not displaying water in Cyan?I can only get this option to work in certain areas. The option is enabled in the FMC.As an example on a flight inbound to KCLE, Lake Erie did not display in cyan on the terrain map.When I load KSRQ or KLGA the water will display in cyan.Also I do not believe that rivers or lakes enroute are showing up either. On my last flight from KTYS to KMEM there were lakes and rivers that I could not see on the terrain map.ThanksDon

I highly doubt rivers and smaller lakes are in the database. That's just way too much extraneous information.As for the issue with Lake Erie, I've never set the option to enabled, so I can't help you there.
