Navigator 1 (NSW)
A gdb file (track & waypoints) recorded on Garmin City Navigator is 1.3mb. I resaved it as a gpx file so I can open it in Ozi but it is now 6.73mb. This is ridiculous!
Is there any other way of converting gbd files to gpx without such an increase in size?
Many thanks,
Rob

Before you save it Rob , you can use filter option in Garmin city Nav , track properties , there are several filter options based on distance points etc.
Typically GPX is about 5 times the size of Gbd , and I can typically filter my tracks to about 1/4 sizein points and still keep accuracy so when saved back as Gbd its only about 1/3rd bigger
Size reduces proportionally this way and you can otimize as you wish.

Dont hesitate to ask for more exact instructions Rob.
It can be a pain if your system saved 30 tracks and you have to filter each one first for example.
A cute trick is to open up a second copy of city navigator and copy and paste just the stuff you want across , and depending of how many you can use the join command to create one big track and then its all easier.
