I have Garmin nuvi LM50 device which bought in India. When I travel to my native place, there are 6 cities crossed and every city has recently(<2years) built bypass road. The default loaded map does not recognize all the bypass roads. I understand that the current map updates does not have bypass roads. When I pass to the bypass, my Garmin device keep recalculating few times and it quit with error like "Could not calculate route"(not sure the exact words). So I have to again set my destination whenever I cross the bypass of every city. It is very hard/irritate me to set destination for 6 times for a trip due unavailability of road in the map source. The google map is properly identify the bypass route. I tried to add the bypass road into the using below steps,
- Create gpx using tyre software
- convert gpx to img ( gpx2img tool)
- GMapTool merge with another SD card map
After doing the above steps, I view the map in the Garmin in all the bypasses and still the bypass road is not found in the map. I am not sure whether my steps are correct or not. Can you please help me to resolve the issue ?
Thanks,
Ramesh
