Finally,
I'm sending in my Garmin 840 xs. We have completely exhausted every update and ducer change.
Now the fine folks at Garmon are ready to accept the fact that is may not be working perfectly.
Note: They will not pay return shipping. I'm not interested in paying 100+ to ship it back with max insurance. Not sure what I'll do but tomorrow, it's heading to Kansas for some well deserved evaluation.
How about just sending my money back and we'll forget the whole thing!
