Deleting waypoints in Nuvi 670

[D G Stewart]

Is there a way to delete groups of waypoints in the Nuvi 670 besides doing
one at a time? I don't see an appropriate file when I have it connected to
my PC.

You should see a couple of GPs eXchange (.gpx) files. I'm guessing
the one you want is called current.gpx. You can edit this file as you
would normally with waypoint management software. I recommend you
first make a backup of this file, then do your editing. If you find
that when you save the file back to your nuvi and the old waypoints
are still there, you will may to delete all my favorites using the
menu on the device before saving the edited file back to it.

I hope this helps you!

I have tried this -even deleted both .gpx files, and the
waypoints are still in the unit... Once you turn the unit
on, the Current.gpx file comes back... So the waypoints are
also stored somewhere else...

The only way I know to delete all the waypoints at once is
to put the unit into the Maintenance Mode...

MAINTENANCE MODE:
Step 1. Turn your Nuvi unit off, remove any SD cards from
the SD card slot and make sure that the unit is not plugged
into
any computer.
Step 2. Place a fingertip on the upper left hand corner of
the touch screen and keep it there while turning the unit
on, a
prompt should read " Do you really want to start in
maintenance mode?"
Step 3. Select the yes button.
Step 4. Enter your PIN if enabled.
Step 5. Main Maintenance Mode screen should have 4
selections:
System information
View Diagnostics
Clear User data
Clear Waypoints
Step 6. After some selections the unit should reboot and you
check to verify unit after rebooting.

Incidentally, Garmin has finally complied with one of our
660 suggestions in the nuvi 760... A new page has been
added: "My Data"... Here one can delete all the waypoints
or just a few selected ones...

Also on that page are:
Set Home Location
Delete Favorite(s)
Delete Route(s)
Import Route from file
Clear Trip Log

However, the 760 comes with no CD manual -you have to
download the .pdf manual from Garmin's site to find out the
above!
