How to

[kumo]

Hi and welcome at RouteConverter forum!

Unfortunately, RouteConverter has problems with decoding GoogleMaps URL's, at this time. This is in work.

To save your weekend, I loaded your URL into an other tool and converted it into a format which can be read by RouteConverter without problems.
Then I used RouteConverter to convert the stuff to Garmin MapSource 6.x (*.gdb).

Here it is:
  lost_again.zip (Size: 842 bytes / Downloads: 752)

If your step-by-step instruction is correct (I don't own a Garmin):

8) connect Nuvi to PC
9) save the file "lost_again.gdb" from the zipped archive to the "garmin" directory on your Nuvi
10) disconnect Nuvi
11) on Nuvi: Tools -->My Data --> import Route from File

Best Regards,
Mathew
