The owners manual for my Oregon 450 does not seem to agree with the menu choices I have on my device. I'm using version 6.20. The Setup Routing description and menu choices are different. Is there or should there be an updated version of the owners manual?Are you using a hard-copy manual that came with the device or the version that's available (free) on-line at the Garmin website? They may both be wrong, but just wanted to make you aware that manuals for all the devices are available on-line.
