I'm new to this and may ask some stupid questions. I have nuvi 3760LMT and trying to make 3790. Let me explain what I did. I took nuvi37xx_GCDFile__470 (I beleive I can use original GUPDATE file from my GPS, if not let me know) opened it in RGN_Tool ,pached it and saved as .rgn file. I didn't change anything in settings of RGN_Tool, because have no idea what they mean. After that I flashed my GPS with this file by using Garmin Web Updater and nothing happened. What wrong did I do? I also read I need .srd files to make voice recognition working, I beleive, I also need some files to make 3D working. Where should I get them?
Thank you.
