If you were doing any time of a flash update, there is no reset.

I have seen many a motherboard thrown away when someone turns off a computer
in the midst of a bios update.. Most hardware/firmware updates do not have
an undo or reset once you start.

Also, I know with Garmin's you can choose the download.. You also agree to
this:
WARNING: If this software is uploaded to a GPS unit other than the product
for which it is designed, you will not be able to operate that unit.

and

Remove the iQue from the cradle. It is very important that the iQue's
battery does not run out during the updating process, so please verify that
it is fully charged. Failure to charge the iQue fully prior to updating the
software may result in a permanent loss of the OS requiring you to send your
unit to Garmin for repair.

and

It is recommended that you disable screen savers or other programs running
on your PC while you go through the update process. Disruptions to the
update process may render your GPS inoperable. If the transfer is
interrupted, turn off the GPS and then turn it back on. Reboot your PC, go
to step #9 and attempt the download again. GARMIN is not responsible for
failed downloads of operating software to the GPS and factory resetting the
GPS unit will fall under our Flat Rate Repair Policy

So it is sometimes easy to make a mistake on an update that requires factory
work..

Sorry to be the bad news man.

Sure hope I don't have to do that.  I can't believe there is not a Reset of
sorts that will let you get to some basic screen and reload the software.  I
have a call into the 800 number, an email into support and I am still
looking for a hidden reset button.
Thanks, Bob Smith
