Hi All,
I have a 10 year old 1197 that has served me well. Recently the screens all locked so I up-rebooted the unit more than once but that didn't fix it.
HBird told me to re-format Nav directory and re-set the Default as well by hitting another button I can't remember the name of.
Those moves fixed the problem but depth is completely whacked out. Sometimes it's right sometime not.
Any help greatly appreciated. Running v.6.3.
