Thank you Catymag for your prompt reply and knowledge.
I have nuvi 1490t which support lane assist. It comes with pre-installed CNNA. Do I need separate junction file for European maps on microSD to be placed in the GPS unit. How should I name it, because there's a file for North America already. Also there's no Garmin folder, the img file is in the system directory.
Can I overcome somehow the "Badajoz, Espana" problem. Is there way to replace this 5.8mb file with 5.6mb from CNEU 2010.20?
Thanks again.
