Thanks manojmat for the India JCV (juctionvew) file. This works fine with my US model Nuvi 1390T with India.NT.2012.20 maps (does not work with MMI7 - If you have both the maps on your GPS storage, then select only IndiaNT2012.20). Have copied the India.jcv file to .system\jcv system folder.
To check if JCV file is working or not, you need to simulate your drive in any major city junction. When simulation starts working, hit the top of map and it will show the visual details. Select any intersection and start pressing up or down key till Junction View button is active (if jcv file is not working the Junction View button will be inactive/greyed). Most likely this JCV file is just the first version that is released so has only few highway exits. It would be great if someone shares updated JCV file or how to edit/add more details to this file.
Thanks to all for sharing.
