at start of ride today my 2610 seemed to be working fine. About 30 miles into the ride it's started doing some strange things. Added a extra (straight line) running off from the route it was running. Keep losing the route, rerouting in wrong direction, etc. Restarted unit and worked ok for a short time than did it again. Restarted again, unit worked but than lost my destination. Did a turn and the route was gone. Thought maybe I screwed up setting up the route but it did the same thing on two different routes I had setup for the ride back home. What the heck? Am running V9 with latest upgrade (first time I have used unit since upgrade) Firmware is up to date. Should I try a hard restart? Will I need to reload my maps if I do this?? Up to today have had no issues with unit. Still under warranty as it's a refurb I got last May.
