I have a love hate relationship with Garmin and my 796. It is like dating a younger woman, it looks good but something always seems to go wrong just when you really need it. Garmin has been very helpful in getting to the bottom of these errors and enhancements and in the next few releases I expect them to fix most of the errors and provide a few new tools which will make the unit as user friendly as my old reliable 396.
