It's possible with RGN_tool put firm of nuvi 1490 (with route gestion) on my nuvi 1310 ?
if yes, what are steps to do it. I have an ESN unit with 5.3 soft version V7 and I get the RGN_tool but I don't know what hwid and sw version I must put and what gdc file I must use.
If not possible by this way, what can I do to get routes gestion on my 1310?
I can modify the firm with an hex editor?
