Please detail installation on sd card for a nuvi 3490
I downloaded and installed in Montana 650 in SD/Garmin/gmapsupp CN India_2012_30 as per some other maps how I did it. But when it was booted, shows " Map can not be Unlocked". But it works on Garmin Nuvi 2565 for car use as SD/map/ India_2012_30. I ll bring only Montana during trip to India. Any advice will be appreciated.
Thank you very much..does it require more space to install?..and vouce files are in english or any indian languages?
better you dont select both at a time
Please upload 2012.40 soon. Thank you
